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.

To make calibration information, do foo. Bhavna
