KolXPD basic items and controls

Item types

Available item types in KolXPD:

- Experiment file: Root for all other items.
- Folder: All items can be organized in folders. Folders can have subfolder of unlimited level.
- Region: One spectrum as wave of X versus Y data.
- MultiView: Graph showing multiple spectra with many instant processing options. Can exist as an item or can be invoked by selecting more regions at one time.

Parameter-resolved experiment items:

 - XPD/ARPES: 1D/2D angle scans - X-ray photoelectron diffraction, Band mapping, etc.
 - Sequence: Time scans or general spectra sequences.
 - NEXAFS/ResPES/...: 1D scans by primary energy (using monochromator at synchrotron) - ResonantPES, NEXAFS, etc.
 - EDAC: Results of EDAC1 calculated XPD pattern. 2D angle data, each angle point contains only a number - calculated intensity.

 - Cluster: Cluster file for EDAC1 XPD pattern calculations.
 - Notes: HTML or plain text.
 - Image browser: Browser e.g. for LEED patterns.

Non-data items for experiment logging:

- sputtering
- heating
- sputtering of hot sample
- exposure by a gas
- deposition

Mouse & Keyboard


  • Selection
    • works like standard windows tree control
    • single selection by single click, browsing by keypad arrows
    • expand/collapse of folder by double-click or click on +/- sign
    • multiple selection by Ctrl/Shift + click
    • multiple selection is adjusted in order to contain items of single type (you can click on some region and that shift+click on a region in different folder - all regions between will be selected but not folders and other items)
    • if you have multiple selection and click on some selected item, other items will not be unselected
  • Arrangement
    • You can move items by drag-and-drop with mouse. Only one item can be dragged now
    • If you hold Shift or Ctrl during drop, item will be copied
    • You can move (reorder) selected items within a folder by pressing Alt + arrows. This works for multiple selection
    • You can cut/copy/paste (multiple) selection. Tip: Items are copied into clipboard as text in same format that is used for saving to files. You can alter text in a notepad before paste back or used its data in other software


  • Zoom
    • Zoom - zoom a region of graph by click and drag a rectangle by mouse. You must start in upper-left corner and go down and right
    • Unzoom - zoom to fit all displayed data by dragging in opposite direction - anywhere in graph from down-right to up-left
    • Pan - if graph is zoomed you can catch it by right mouse button and move
  • Range - used to define a part of a wave for subsequent processing, e.g. area and background computing, fitting, export, etc.
    • If displayed wave(s) has defined range and can be modified, range borders are displayed by black vertical lines with hatching
    • You can move with a border by dragging and holding Ctrl key
    • If you hold Ctrl and Shift it will move both borders simultaneously
    • Graph can have a Set range button nearby for other range manipulations
