Data Files

The programme offers several routines for file loading, because the different software applied for spectrum acquisition produces different data formats. The programme has to access the original spectrum from time to time. Therefore, the memory device with the experimental data should not be removed or changed during the processing. Single spectra, multi-region measurements, parameter dependent measurements, line scans and multipoint (area) scans can be loaded. The acquisition parameters peak name, comment, batch parameter, analyser mode (RAMAN: exposure mode), pass energy (RAMAN: Grating), lens mode (RAMAN: Slit), excitation energy (RAMAN: laser wavelength), start and end energy (RAMAN: start and end wave number), dwell time, number of accumulations, x position and y position can be corrected or changed after loading the spectra using a special sub-menu of UNIFIT. Examples of measurement data are saved on the install USB-memory card:
XPS: XPS_Measurement_Reference_Data,
XAS: XAS_Measurement_Reference_Data,
AES: AES_Measurement_Reference_Data,
RAMAN: RAMAN_Measurement_Reference_Data.

Open Spectra

This menu contains all loading routines available at the moment created on different user demands. Several regions can be loaded for some of the data formats. The names of single regions (e.g. C 1s, S 2p, O 1s, etc.) should not be used twice. The examples for experimental data files are summarized in the book ‘Line Positions and Data Formats – Version 2018’. The directory accessed the latest is selected automatically. Therefore, do not remove the memory device with the experimental data. The previously applied loading routine is opened if the icon is used. Measurement files with the same name cannot be opened simultaneously. In case of
1. parameter dependent measurements the batch parameters (sputter time, angle …) will be added with an underline to the region name (e.g. Si 2p_0, Si 2p_5, Si 2p_10, etc.),
2. multipoint measurements (all regions have the same batch parameter) the new batch parameters is created using the X and Y position, the region name displayed in the title lines of the windows will be modified with the batch parameter (e.g. region name: Si 2p, X position: 10, Y position: 35, region name: Si 2p_10|35),
3. parameter dependent multipoint measurements the region name displayed in the title lines of the windows will be modified with the batch parameter, the X position and the Y position (e.g. region name: Si 2p, batch parameter: -90, X position: 10, Y position: 35, region name: Si 2p_-90|10|35).
The decimal character of the data has to be a point. A maximum of 75600 spectra can be loaded simultaneously. In case of multipoint (area) scans the batch parameter will generated by the x and y positions (e.g. x position: 12, y position: 25, resulting batch parameter: 12|25). The usage of a SSD hard disk may considerably reduce the loading and processing time of projects with a large number of spectra. All acquisition parameters may be modified at point.

1. XPS Data Format

The XPS measuring data (with the exception of snapshot scans) have equidistant step widths and a monotone increasing or decreasing energy scale.

1.1 ESCALAB Eclipse (*.TAP;*.TXT)

The sub-menu ESCALAB allows to load data from the Eclipse programme (ESCALAB220iXL), generated by the Eclipse sub-routine 'data export' in ASCII and saved with the extension *.tap (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.1).

1.2 ESCALAB/K-ALPHA Avantage (*.AVG)

The sub-menu ‘ESCALAB Avantage’ allows to load data from the Avantage programme, generated by the data export programme C:\VGScientific\Software\bin\DataSpace BatchDump.exe in ASCII and saved with the extension *.avg (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.2). This routine allows the data transfer of one single region (e.g. C 1s or O 1s…) but also the conversion of parameter dependent measurements (e.g. angle resolved measurement, seven regions, 0 – 60°: C 1s 0°, C 1s 10°, …, C 1s 60°), the loading of line and multipoint (area) scans. The x and y positions of the recording points are available. In case of a multipoint scan the batch parameters are generated using the x and y position (x|y).
Additionally, parameter dependent multipoint measurements are loadable. Then the batch parameter includes the value of the batch parameter (e.g. sputter time), the x position and the y position (e.g. SDP multipoint measurement: batch parameter = sputter time|x position|y position). 

1.3 ESCA3 (*.TAP)

This menu option initiates the loading routine for a data format provided by special software developed for a VG ESCA3 spectrometer at the University of Leipzig (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.3).

1.4 BESSY/VSI/HHUD (*.*)

With the sub-menu BESSY/VSI/HHUD it is possible to load experimental data like those recorded with the EMP software from the synchrotron storage ring BESSY. A dialogue box asks for excitation energy and region name, because they are not included in the data file (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.4 – 3.1.6).

1.5 CAF/KRATOS (*.*)

This menu item is developed for loading data in its simplest form with the energy in the first and the intensity in a second column. All remaining parameters are to be provided in a separate dialogue box. Start and end channel must be given as kinetic energies increasing from start to end. The start energy is used for controlling the data format (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.7 – 3.1.8).

1.6 PHI-5400/5600 (*.INF + *.ASC)

The software used with PHI-5400 spectrometers provides the experimental spectrum (*.ASC) and the acquisition parameters (*.INF) in two separate files. After selection of this menu option, the *.INF file will be opened. The programme searches for the *.ASC file with the same name and opens it. The specific PHI peak names are converted into usual designations during the loading process (e.g. Ag1 to Ag 3d) (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.9).

1.7 PHI-545/590 (*.TXT)

The software of the PHI-545/590 spectrometers permits the export of the spectra as txt-files. These created data files can be loaded with the programme UNIFIT. Three different measurement formats can be generated: single region, multi region and profile measurement format. For a correct handling of the data with UNIFIT the regions should have the usual designations (Ag 3d, Cu 2p3…) (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.10).

1.8 PHI-1600/1600C (*.CSV)

The measurement data of the spectrometer PHI-1600/1600C can be exported as ASCII data. The acquisition parameters are saved at the top of the file. The intensities of the regions are saved at the end of the file. The CSV format allows the saving of standard spectra as well as parameter dependent measurements (see book ‘Line Positions and Data Formats – Version 2017’ 3.1.11).

1.9 VGX-900 (*.1)

The software VGX-900 supplied with VG spectrometers currently produces two files for one set of data. UNIFIT handles the measured data file in combination with a dialogue box asking for the excitation energy. The experiment name has to start with XPS (xps) or AES (aes), if the spectra were recorded with decreasing kinetic energy and with XPSREW (xpsrew) or AESREW (aesrew) in case of increasing kinetic energy. Up to ten regions can be loaded simultaneously. In case the experiment does not have the structure shown above, a dialogue is opened for specification of the scan direction (decreasing or increasing) and acquisition energy (BE or KE). Parameter dependent (angle, sputter time) series of spectra collected with the VGX software can be loaded directly in the programme UNIFIT as well. Only files with the same name but consecutively numbered extensions are interpreted as batch. The extension is used by UNIFIT as batch parameter (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.12).

1.10 VAMAS (*.VMS;*.NPL)

The VAMAS format is developed especially for chemical surface analysis with XPS. It allows transferring standard spectra, parameter-dependent measuring series (depth profiles, XPD‘s...), line scans, multipoint (area) scans as well for further treatment (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.13). The x and y position of the recording point is available. Special options (normalization or sum operation) of the input may be selected in the menu point [Preferences – Import – VAMAS (*.VMS;*.NPL)]. In case of a multipoint scan the batch parameters are generated using the x and y position (x|y).
A series of files of a batch measurement can be loaded automatically. The batch indicator is a five-digit number (e.g. Test_00001.vms, Test_02156.vms). The loading procedure starts from the selected file. If a file is available with a batch indicator will be greater than the old value by one, than the file are loaded additionally and so on (e.g. Test_00001.vms, Test_00002.vms, Test_00003.vms, Test_00005.vms are saved, Test_00001.vms is selected, the files Test_00001.vms, Test_00002.vms and Test_00003.vms are loaded). All loaded regions get the measurement file name from the first one.

1.11 VAMAS (*.VMS;*.NPL) Clipboard

ClipboardMeasurement data recorded the VAMAS format and stored in the clipboard can be loaded using this menu point.

1.12 NPL (*.NPL)

The current VAMAS-format was developed from the NPL-data record type. Like VAMAS, the NPL-format also contains the most important measurement data, but it is less extended than VAMAS (see book ‘Line Positions and Data Formats – Version 2020’, 3.1.14).

1.13 SPECSLAB (*.EXP)

This input routine is able to read the measurement data recorded with the programme SPECSLAB especially used by the spectrometer of the SPECS brand. Data from normal as well as parameter dependent measurements are accepted. To enable UNIFIT to correctly interpret the data, it is essential that the correct name of each region (e.g. S 2p, Au 4f7…) is stated in the acquisition parameter box “tag:” before the spectra are recorded. Intensities are read from the data set “original:” (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.15).

1.14 VSW-Tübingen (*.DAT)

This special data format was implemented into UNIFIT for a spectrometer build by VSW for the University of Tübingen. The exact data structure is shown in the book ‘Line Positions and Data Formats – Version 2020’, 3.1.16.

1.15 VGS2000 (*.XPS)

This input routine reads a special data format of the University of Giessen. The excitation energy is specified using a separate dialogue box. The intensities are saved as cps (see book ‘Line Positions and Data Formats – Version 2020’ 3.1.17).

1.16 ScientaSES-Signals (*.TXT)

This special data format is used from the research centre of Karlsruhe (SES software). The energy values have to be stored as kinetic energy (see book ‘Line Positions and Data Formats – Version 2020’, 3.1.18).

1.17 ScientaSES-Spectra (*.TXT)

This special data format is generated by the Scienta spectrometer working with the SES software. The intensities split in small angle or Y-axsis regions (Number of slices) are saved in several columns. Two reading options are available;
1. The sum of all slices gives the intensities of the spectrum. Using this option, a series of files of a batch measurement can be loaded automatically. The batch indicator is a four-digit number (e.g. Test_0001.txt, Test_2156.txt). The loading procedure starts from the selected file. If a file is available with a batch indicator will be greater than the old value by one, than the file are loaded additionally and so on (e.g. Test_0001.txt, Test_0002.txt, Test_0003.txt, Test_0005.txt are saved, Test_0001.txt is selected, the files Test_0001.txt, Test_0002.txt and Test_0003.txt are loaded). All loaded regions get the measurement file name from the first one.
2. The intensities of every slice are loaded in separate spectra (e.g. 3 regions, 100 slices, 300 spectra are generated), (see book ‘Line Positions and Data Formats – Version 2020’, 3.1.19).
Multipoint measurements or line scans can be loaded if a third dimension is available (1. dimension: energy, 2. dimension: slice parameter, 3. dimension: stage position). In case the name of dimension 2 is 'Y-Scale' then the slice parameters are loaded as y position. The position of the stage defines the X position.

1.18 PHI Spectrometers/Single Spectra (*.SPE)

This special different data formats (different software versions) are used from the PHI Spectrometers (e.g. VersaProbe, Quantera, …). The acquisition parameters are saved from the line SOFH to line EOFH using the ASCII-text format. The intensity values are stored at the end of the file in single or double float format. The number of bytes of the saved intensities is four or eight times higher as the number of channels of all regions (book: ‘Line Positions and Data Formats – Version 2020’, 3.1.20.1).

1.19 PHI Spectrometers/SDP/ARXPS (*.PRO;*.ANG)

This special different data formats (different software versions) of profiles or mappings (SDP, angle-resolved measurements, etc.) is used from the PHI spectrometers (e.g. VersaProbe, Quantera, etc.). The acquisition parameters are saved from the line SOFH to line EOFH using the ASCII-text format. The intensity values are stored on the end of the file in single or double float format. The number of bytes of the saved intensities is four or eight times higher than the number of channels of all regions (book: ‘Line Positions and Data Formats – Version 2020’, 3.1.20.2 (*.PRO), 3.1.20.3 (*.ANG) and 3.1.20.4 (*.MAP)).

1.20 Focus CSA (*.DAT)

This special data format is used by the spectrometer Focus CSA (a special analyzer for high energies). Only one region will be saved. The header includes the recording parameters (e.g. start-, end- and excitation energy, step width, etc.). The data set with five columns includes the sum spectrum [DATA] and the single scans [DATA 1,…,[DATA 20]. The columns are: energy, intensity, three normalization values (book ‚Line Positions and Data Formats – Version 2020’ 3.1.21).
The file name is used as spectrum name. Additionally, a batch parameter can be defined. The input routine allows the reading of the sum spectrum or the single scans. With the selected single scans a new sum curve can be created. If single scans are loaded the spectrum name is expanded by the scan number. A spike test of the single scans and a preview can be made automatically. An optional normalization using the values of the column 3 – 5 can be carried out. The maximal number of loadable or presentable scans is 100.

1.21 Croissant (*.PESP)

This special data format is used by the University Basel. Only one region will be saved. The header includes the recording parameters (e.g. start-, end- and excitation energy, step width, etc.). The data set with eight columns includes the binding energies, the kinetic energies, the sum intensities (is loaded) and the intensities of each channeltron (book ‚Line Positions and Data Formats – Version 2020’ 3.1.22).

1.22 SSI XPS (*.MRS)

This special data format is used by the University Stanford. Only one region is saved. The header includes the recording parameters (e.g. start- end energy, step width, excitation energy, ...). Only the first data block is loaded (s. book ‚Line Positions and Data Formats – Version 2020’ 3.1.23).

1.23 SPECS Phoibos225 (*.XY)

This data were generated from a special converter of the spectra recording software SpecsLab. The SpecsLab software offers the following eight generation options:
- Counts Per Second:            yes/no,
- Kinetic Energy Axis:            yes/no,

The acquisition parameters are stored in the header (s. book ‚Line Positions and Data Formats – Version 2020’ 3.1.24). Multipoint (Area) scans include the x and y recording position of every region.
The step width of snapshot scans is not equidistant. Therefore the energy values of the intensities are not used from the original data. The energy values and the step width are calculated using the initial and final energies and the number of the snapshot channels. The average energy values have uncertainties with respect to the original data of less than ±0.02 eV.

1.24 HTW Berlin (*.DAT)

This special data format was implemented into UNIFIT for a spectrometer of the HTW Berlin. The exact data structure is shown in the book ‘Line Positions and Data Formats – Version 2018’, 3.1.26. The data comments are in German. The decimal delimiter is the comma. The first column is the energy axis in KE. The third column includes the intensities.

1.25 1. Column: BE decreasing/Following Columns: Intensity (*.*)

2. XAS Data Format

XAS measuring data can be stored in non-equidistant step width and the energy scale not necessarily needs to be monotonously rising or falling. During reading data are converted into data with equidistant step width. Not available intensity values are calculated by linear interpolation. Before reading the data are ordered according to the energy values and the step width. The smallest generated step width is 0.01 eV. The input of XAS data changes the labelling of the X-axis to 'Photon energy / eV'. All opened windows presenting an XA spectrum get an internal XAS sign for the special programme control XAS.

2.1 NEXAFS (*.DAT)

This special input routine reads data with non-equidistant step widths typical for NEXAFS measurements. Firstly the smallest step width sw of the data set will be estimated. Secondly the spectrum is converted to an equidistant form with the step width sw and a new number of data points. Not available intensity values are interpolated linearly. The X-axis will be annotated with ‘Photon energy / eV’. All necessary recording parameters (pass energy, dwell time…) have to be inserted manually (book ‚Line Positions and Data Formats – Version 2020’ 3.2.1).

2.2 BESSY-EMP/2 (*.*)

The data are saved in a number of columns. (1. Column: Photon energy (increasing), next columns: intensity, reference data). The recording parameters are saved in the header (number of data points, dwell time...). A variable reading routine allows the allocation of the different columns to the correct data form. The intensities can be normalized optionally using reference data.  (book ‚Line Positions and Data Formats – Version 2020’ 3.2.2). Start energy, end energy and step width of the input can be changed optionally.

It allows transferring standard spectra, parameter-dependent measuring series (depth profiles, XPD‘s...), line scans, multipoint (area) scans as well for further treatment (see book ‘Line Positions and Data Formats – Version 2018’ 3.1.13). The x and y position of the recording point is available. Special options (normalization or sum operation) of the input may be selected in the menu point [Preferences – Import – VAMAS (*.VMS;*.NPL)]. In case of a multipoint scan the batch parameters are generated using the x and y position (x|y)(book: ‘Line Positions and Data Formats – Version 2020’, 3.3.1).

3.2 PHI Spectrometers/Single Spectra (*.SPE)

This special different data formats (different software versions) are used from the PHI Spectrometers (e.g. PHI 700, PHI 680, …).

This special different data formats (different software versions) of profiles. line scans or mappings (SDP, angle-resolved measurements, etc.) is used from the PHI spectrometers (e.g. PHI 700, PHI 680, etc.). The acquisition parameters are saved from the line SOFH to line EOFH using the ASCII-text format. The intensity values are stored on the end of the file in single or double float format. The number of bytes of the saved intensities is four or eight times higher than the number of channels of all regions (book: ‘Line Positions and Data Formats – Version 2020’, 3.3.2.2 (*.PRO) and 3.3.2.3 (*.MAP)).
If the x-y points at the enery E of a mapping have one intensity value I only, two additional points are generated during the input routine (I(E - 1) = I(E)/100,I(E) = I(E), I(E + 1) = I(E)/100).

3.4 1. Column KE decreasing / Following Columns: Intensity (*.*)
