Overview

Multi-gain range detectors are more complex than previous LCLS detectors and calibration constants are not calculated by calibman.

NOTE: The "-h" option for all commands shows common example syntax, as well as descriptions of parameters.

All constants except jungfrau pedestals (gains, offsets, pedestals) are stored in /reg/g/psdm/detector/gains/epix10k/panels/ and /reg/g/psdm/detector/gains/jungfrau/panels/ and are copied by the scripts below to the calib-dir.

Epix10ka

DAQ needs to collect charge-injection xtc file for offsets.

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.

Offsets must be available before pedestals, because pedestal calculation depends on offsets.

Commonly used commands:

epix10ka_offset_calibration -h
epix10ka_pedestals_calibration -h
epix10ka_deploy_constants -h

The deploy command

• must be done after either the offsets or pedestals have changed, or 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
