Preserving intermediate fit results for debugging

For debugging purpose, intermediate fit results are preserved in temporary *.npz file like

<repository>/<panel-id>/work/epixhr2x2_0001_19900121012401_ascdaq18_r0171_sp05_df.npz

If this file is available, data processing is omitted, but final pixel status evaluation and resulting plots can be repeated. To re-process data this file must be deleted.

Parameters for debugging

-S NSIGM, --nsigm NSIGM - defines range of the good pixel status

--slice SLICE -  sets a part of the penel to be displayed on plots

-D, --display ,etc.- turns off plots that reduces processing time

  • charge injection processing for epixhr is ready
  • test 1single-ASIC panel contains a lot of dead and noisy pixels
  • H and M gain modes shows significant non-linearitypixel status is evaluated for this procedure
  • fit results in terms of offset and gain constants are saved along with chi2 and pixel status arrays
  • Philip: at 1st stage this script will be used for detector characterization
    • pedestals are not re-evaluated
    • gains are not used directly
