 > On a separate note, the online monitoring software (hummingbird, by Benedikt and Filipe) will need py+psana. However, the default psana calibrations/corrections for the 140k back detector seems wonky. You might recall that there was a teleconference where Veitâ's student (Yi-Tien) discusses how the 0-photon peak had a largish negative ADU, despite turning on common mode correction and dark subtraction (psana's implementation). Would you and your team be able to take a look at these as well? If  it's a quick fix, then the online monitoring group will have a much easier time (e.g. they won't have to separately do common mode subtraction).

Use psana configuration file psana-cxidg3-cspad2x2-NDArrAverage.cfg (download), which can be executed by command:

Code Block
sit_setup
psana -c psana-cxidg3-cspad2x2-NDArrAverage.cfg exp=cxi86415:run=7

This job produces 3 files with cspad2x2 shaped arrays for averaged, rms, and maximal intensities.

These arrays can be plotted by the command

Code Block
plims cspad2x2-ndarr-ave-cxi86415-r0007.dat

Results for runs 7, 62, and 83 are shown on plots:

These plots show that the dark level is consistent with zero and does not indicate on any offset.
