Michal's current implementation has very limited use. Need to improve the GPU engine for applications at the APS.

Checkpoints:
Scan positions

  • Linear trajectory: perfectly rectangular grid
  • Linear trajectory: rectangular grid w. missing scan points
  • Linear trajectory: rotated rectangular grid
  • Continuous trajectory
  • Load external positions

Algorithm:

  • Probe initialization
  • Mixed-state + arbitrary-path fly-scan
  • Constant vs. varying probe intensity
  • Position correction
  • Variable probe correction
  • Online FSC estimation
