Overview
Multi-gain-range detectors are more complex than previous LCLS detectors and calibration constants are not calculated by calibman, but instead using scripts described here.
...
- must be done after either the offsets or pedestals have changed
- can be used when creating a new experiment.
- it requires an existing expt/run-number so it can see the panel-id's and copy the appropriate constants into the experiment calib-dir

Jungfrau
The detector group must provide all gain/offset data for jungfrau.
Commonly used commands:

---|
jungfrau_ndarr_dark_proc -h jungfrau_deploy_constants -h jungfrau_gain_constants -h (done more rarely by psana/detector experts) |
The "jungfrau_gain_constants" script can be used to setup the calib-dir for a new experiment.
Example of deployment geometry files:
geometry_deploy_constants -e cxic00121 -r 75 -d CxiDs1.0:Jungfrau.0 -D
