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
...
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 you expect us to do about improve bad pixel mask improvement?
A:
- their code is terrible
- re-implement and try their algorithms
- Q: need help in analysis algorithms to check with the bad pixel mask to estimate its performance
- hit rate
- indexing efficiency
A 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"
