Collection of Python scripts for analysing momentum-resolved energy-loss spectra taken in a transmission electron microscope.


  • aperture: angular correction for TEM and STEM-EELS. See 1.
  • ecal: energy calibration using spectra shifted in energy
  • qcal: momentum calibration using a shifted aperture
  • runscripts: scripts for performing energy- and momentum calibration and extracting spectra from a measured WQmap
  • gui: minimal GUI for viewing WQmaps
  • tools: set of useful functions (constants, image analysis,...)
  • tests: example data for running self-tests
