Hi, 
You could try to use the gain files obtained with the pulser. They are not great but might work.

For a better gain calibration, we should use single photon data. 
There is sufficient 1 photon data taken during the first testing at XCS,
but it will take me a few days to calculate the gains.

I would actually advocate returning the number of photons (as we 
discussed in a meeting a few months ago). Even without a calibration it 
can be easily calculated from the (average) gains:

High (FH and AHL): 132 ADU/9.5 keV
Medium (FM and AML): 43 ADU/9.5 keV
Low (FL, AHL, AML): 1.32 ADU/9.5 keV

(Just a note, while the pulser is not great for calibrating gains, it works fine for offset calibration)

Thanks,
Gabriel
