Hi Philip, I just checked this with Angelo, the number we should use are the ones from the 10kT, which means:

H   M    L 
1  1/3   1/80

**) Dionisio: We will get the measured gain values with the  upcoming tests. For now we can estimate them using the expected gain ratios between high to medium and high to low gains respectively  x3.925 and x141.6.

***) Dionisio: Last time we measured we got for the Cd sealed source ~22000/900ADU = 24.4eV/ADU

Philip: I think 24 ev/ADU should be for high gain - 100 counts would be 2.4 keV, more or less the photon it's aimed at.
