"""
All jungfrau runs are taken through one acquisition, except for the forceswitch runs.
While taking non-fixed dark runs, a procedure of multiple acquisitions is used to switch the storage cell indices.
This is done for medium and low gain dark dynamic runs, only [forceswitchg1, forceswitchg2]:
Switching the cell indices in burst mode is a work around for hardware procedure
deficiency that produces wrong data for dark runs except for the first storage cell.
This is why multiple acquisitions are taken to switch the used storage cells and
acquire data through two cells for each of the 16 cells instead of acquiring darks through all 16 cells.

## Bad Pixel Map ###
The bad pixel map is deduced by comparing offset and noise of each pixel ($v_i$) and each gain ($g$) against the median value for that gain stage:
$$
v_i > \mathrm{median}(v_{k,g}) + n \sigma_{v_{k,g}}
$$
or
$$
v_i < \mathrm{median}(v_{k,g}) - n \sigma_{v_{k,g}}
$$
Values are encoded in a 32 bit mask, where for the dark image deduced bad pixels the following non-zero entries are relevant:
