Examples

• PyExtal example for CBED refinement
  • load data
  • set detector parameters
  • initialize diffraction info class
  • region of interest parameters:
  • initialize coarse refine
  • initialize fine refine for structure factor
• Structure Factor refinement of Si LARBED 111 systematic row
  • load Larbed data
  • initialize the diffraction info class
  • define parameter for region of interest:
  • select the region of interest
  • initialize coarse refinement
  • refine orientation and thickness of the sample and display the results
  • reselect the region of interest for fine refinement
  • set parameters for fine refinement
  • set initial structure factor parameters
  • perform fine refinement
  • display the kernel (probe shape in reciprocal space)
  • display the results
• High voltage calibration example
  • load data
  • initialize diffraction info class
