Dear Phil, Mikhail and Chris,

   Sabine provided me with the mask they are using. You can find it at:
~valmarpsana-extra-extreme-sabine2.h5

Like the name suggests, it goes to the extreme in masking stuff. It looks more or less like the attached screenshot.
Sabine says she is working on another mask, which I will pass to you as soon as I get.
Thank you!
Valerio

Subject: JF4M status
 
Hi, I'm looking a bit at the report of damaged JF4M pixels following an ice (?) event.  I see we've gone from ~261 official bad pixels to ~1931 and now have ~520 more pixels stuck in low when autoranging (id est, in 'Normal').  A simple script to capture this information and look at pixels stuck in the wrong state for a pedestal run is
~philiph/psana/jungfrau/2021/badSwitchStatus.py.

E.g.,

psanagpu103:~/psana/jungfrau/2021$ python badSwitchStatus.py cxilu7619 168
mode is Normal
found 4194254 pixels in Normal
found 20 pixels in Med
found 30 pixels in Low
mode is Med
found 29 pixels in Normal
found 4194273 pixels in Med
found 2 pixels in Low
mode is Low
found 23 pixels in Normal
found 3 pixels in Med
found 4194272 pixels in Low
number of bad pixels overall: 261

psanagpu103:~/psana/jungfrau/2021$ python badSwitchStatus.py cxilv1019 142

found 4193737 pixels in Normal

found 550 pixels in Low
