Hi Mikhail,
We've collected some silver behenate rings on ePix10k-2M.1 last night in mfxc00118 experiment. Run 243 is the same as 242 + 30 mm in Z, 244 is the same as 243 + 30 mm in Z.
Best wishes,
Alex |

commands to process:
geometry_image -g geo.txt -a mfxlx4219_0048_epix10k2M_mean.npy -R50 --amin 0 --amax 30 -s recentered
geometry_image -g geo.txt -a mfxlx4219_0048_epix10k2M_mean.npy -R50 --amin 0 --amax 30 -s lab-frame -C1
Images for re-centered geometry psana frame (-C0)
Images for re-centered geometry LAB frame / crystfel (-C0)
Command to convert psana to crystfel format:

In mfxp21319-r0014 averaged/max over 10k events image contains crystal diffraction pattern which does not allow visually re-center detector. Single bright ring is most likely from scattering on nozzle or mount, which has nothiong to do with sample. BTW, default geometry with 0 offsets works good.
