Psana reports in keV (using about 16 ADU/keV) as of run 21.
Each camera is calibrated at the ASC using our x-ray generator or using a sealed source, typically in situ. Currently the RGD is offline awaiting safety approvals. Cameras that have not been calibrated get an approximate constant calibration of 0.06 keV/ADU. The gain file is deployed by makepeds the first time it is run. Makepeds looks for the pixel_gain directory under the experiment /calib directory. Psana and AMI use the gain file to report keV.
