Hi Mikhail and Mona,
Shall we try to compare cxic0415 run84? This is a dark run.
Run85 is a light run.
Cheetah bad pixelmap is here.

Best,

Hi Mikhail,

Here is the mask for bad pixels generated from cctbx.
/reg/d/psdm/cxi/cxid9114/scratch/mona/s1/discovery/mask_cxic0415.txt
The 0’s are the bad pixel. I used r86 as Dark run and r100 as light run.
I hope my understanding of their 64 x 185 x 194 format is correct. I also sent an email to Aaron. I’ll let you know again if the format is not right.
Cheers & Happy Thanksgiving!
Mona
