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.
...
The DAQ and detector groups provide scripts to generate special xtc files in various gain ranges and (for epix10ka) charge-injection.
Epix10ka
Both dark/offset calibrations do not have to be done for all gain ranges. The calibration system will insert dummy constants for the gain ranges that are not included.
...
- 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
Example Deploy geometry files:
geometry_deploy_constants -h

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
