Examples assume that processing is done on detdaq18 run 80 or 92. These parameters needs to be substituted in actual processing.
Offset and gain calibration
Regular offset and gain calibration
Script epix10ka_offset_calibration works on special runs containing 103 calib-cycles = 5 dark + 2 x (7x7) charge injection.

JFTR, under ~/philiph/psana/mfxc00118/mfxlx4219
I have run
python deployOfficial10kOffsetsV2.py MFX
source deploy_offsetph_constants.sh
with output
2021-10-13-r384-log-epix10ka-deploy-constants
and now we have what look like sensible AML-L pedestals.
Bhavna, we should officialize this during in a calm in the storm.
Thanks,
Philip |
Example for population of the offset directory with correct names is in
https://github.com/lcls-psana/Detector/blob/master/examples/ex_epix10ka_save_ctype_in_repo.py
Formulae for pedestals of AML-L and AHL-L is changed by Philip's request,
AML_L pedestal = FL + offset, if offset is available, otherwise 0 (or can be changed to FL).
Pedestal calibration

Geometry
Geometry constants generated from optical metrology (see dates in directory names) and data tuning in psana format resides under
/reg/g/psdm/detector/alignment/epix10ka/
/reg/g/psdm/detector/alignment/epix10ka2m/
/reg/g/psdm/detector/alignment/epix10kaquad/
The last line of the geometry file needs in adjustment of the detector position relative IP.
Constants needs to be deployed under <experiment>/calib/
directory using command in lcls environment set by source /cds/sw/ds/ana/conda1/manage/bin/psconda.sh
like
calibfile deploy -h
