Description

@tgruene

I also just noticed that the data file (e.g. /data/epoc/storage/jem2100plus/UniVie/Bismarck/PHVE39/2025-02-28/1200_powderrings_image_2025-02-28_1954_data_000001.h5) contains an entry /entry/detector/timestamp for each frame. The difference between consecutive numbers is 500050, not 500000. This piles up between frames. @khalil: would you discuss with Filip the meaning of the offset +50 from 500000? It affects the rotation rate by 0.0001% This is little, but it is there.and would mean that instead of 150.000 degree, the data covers 150.015 degree, which is not too far off from the precision of unit cell axes. The entry 'timestamp' lacks a unit, presumably ns.?
