Author: European XFEL Detector Group, Version: 1.0
The following is a processing for the dark constants (`Offset`, `Noise`, and `BadPixelsDark`) maps using dark images taken with Gotthard2 detector (GH2 50um or 25um).
All constants are evaluated per strip, per pulse, and per memory cell. The maps are calculated for each gain stage that is acquired in 3 separate runs.
The three maps are of shape (stripes, cells, gains): (1280, 2, 3). They can be injected to the database (`db_output`) and/or stored locally (`local_output`).
