Hi Mikhail,
I came across a user working on xpplw3319 dataset. It seemed that our LCLS mask was not sufficient for their analysis.
Please see attached 4 detector averaged over multiple events and 4 detector masks (run293, epic_alc1,2,3,4).
Do you think setting more conservative parameters in selecting bad pixel map would help in this case?
Best,
Chuck

Dark average (pedestals) and pixel_rms images with spectra

epix_alc1

epix_alc2

epix_alc3

epix_alc4

Interim Summary

  • In alc1 two data banks look different from other banks, but they are not so bad to discard them by changing thresholds.
  • The "scratch" in alc3 is not seen in dark.
  • The number of bad/discarded pixels can be changed by variation of thresholds.

Summary of the mtg with Chuck

Discuss article Automatic bad-pixel mask maker for X-ray pixel detectors with application to serial crystallography

  - Q: definition of robust parameters
    A: robust mean is median xi
        robust sigma is median |xi-mu|
  - Q: difference in algorithms
    A:
    - for dark intensity and rms algorithms are about the same
    - Philip evaluated gains for a few detectors

       - but in general we do not have/use bad pixel status for gain factors (generated from flat field)

       WE NEED IN LIGHT FLAT FIELD DATA IN ALL GAIN RANGES ALONG WITH DARK

       - for gain and bad pixel status

  - Q: What can we do to improve bad pixel mask?
    A:
      - their code is terrible
      - re-implement and try their algorithms
  - Q: need help in analysis with the bad pixel mask to estimate its performance
       - hit rate
       - indexing efficiency
     A: - Chuck's team can do that
  - Chuck: start with "flat field" sample for epix_alc3 and try to find bad  pixels "next to central row and "scratch"

  • median of frame intensity is int. Variation between frames is very small ~ +/- 1 ADU
  • median spread is also int 0
  • can't set med +/- 8 spr limits... does not work if implemented as described in Article
          -> if spread is 0 it is evaluated as std

Feature 2 and 3 for dark run

Implemented on 2023-04-06 exactly as described. Median is used for robust statistics parameters evaluation.

Feature 4 and 5 for gain modes

TBD

Feature 6

Pixel status after Feature 6 and our regular mask after dark processing and averaged data

  • Feat. 6 adds more bad pixels, especially stripe in the lower right ASIC
  • "scratch" seen in data is not reproduced

Chuck wants to find "scratch" automatically

2023-04-06 Feature 2 and 3 for dark data vs our standard dark processing

  • dark data set: exp=xpplw3319:run=287
  • detector: XppGon.0:Epix100a.3, alias: epix_alc3
  • This data set contains ~1200 events, of which initial 1000 is used in processing.
  • By default features 1,2,3 are used. Feature 4 and 5 for gain factors are not implemented and are irrelevant to epix100a.
  • Feature 1 - good frame selection discards 1/0/0 frames for SNR=3/5/8, respectively


Results for SNR max = 3,5,8

Interim summary

  • Number of bad pixels depends on SNR parameter
  • Stripe of bad pixels in the middle of the detector can be caught by Feature 3 and 6 at SNR=5.
  • "Scratch" observed by Chuck is not seen detected ...

2023-04-07 mtg summary

  • Chuck: try to search for scratch in ASIC ONLY!
  • Chris: try to change gate limits in dark processing to reproduce bad pixel in the middle stripe.
