Why do I think that 2020-02-25 optical metrology is good
- very good quality check
- all z-measurements are around 1 feet, have a lit of repeatable numbers - can't be trusted
Quality check for original optical metrology from 2020-02-25

Images of panels in data for all detector orientations in metrology processing v1 without quads
- v1 of the metrology processing script represents simplest approach - each panel coordinates are taken as is to insert in the detector
- data from mfxc00118 run44 silver-behenate sample
Summary:
- numeration of quads at rotation looks symmetric - so seems right
- one orientation of the detector gives correct image and it shows smallest offsets between panels in quads

Geoptimizer or how geometry can be screwed-up if it is applied blindly
First thanks to Olexandr and Marina for discovering how our geometry should be mapped to data array.
However, as an intermediate step geoptimizer returned geometry which is significantly different from optical metrology, as shown in movie as comparing panels before (from opt metrology) and after optimization.
It is clear that blind application of geoptimizer may cause >1 mm offset of panels...
