Intro

In April 2021 we introduce a new approach to dark processing for Jungfrau detectors. This approach is pretty much similar to epix10ka dark calibration. Entire dark calibration is split for two stages. At first stage specialized dark runs for three gain modes or "drop-shots" for regular runs are processed per-panel and results are saved in the repository also per panel. At second stage, per-panel constants are merged for particular detector or set of panels (for DRP) and deployed in the regular calibration directory.
