Due to a recent hardware intervention, a bank of pixels of EPIX-1 at HED is dead. These were not being classified as bad pixels in the Dark Characterization NB, becuase the sigma tolerance for offset deviation was to high (5). Reducing it to 2 fixes it (this is the highest integer that does so).
Running the notebook interactively for p900338, r176, for EPIX-1 and EPIX-2. EPIX-2 was used as control, and no significant changes in the number of bad pixels for this detector was observed after reducing the sigma tolerance for offset deviation.
