| 2018-04 | DsaCsPad | Cu | cxilr6716 | gain_prelim.npy | From Derek Mendez: Its not perfect but seems to improve the data (pretty important for the correlations experiment). Interestingly in this camera there is also a lone quad that is off. The initial goal was to measure an intensity-dependent gain correction (hence the different transmissions), but for now I just use the average gain cal from these data. One such average-gain map is stored as a 3D numpy array (same shape array returned by det.raw(event) ), this is in cxilt1417/scratch/gain/gain_prelim.npy* . the correction would be >> gain = np.load("gain_prelim.npy") >> assert ( np.all(gain!=0) ) >> data = det.calib(None) >> data /= gain |

Note: Pnccd has numbered gain modes.
Kaz says that PNCCD gives out ~1250ADU per 1keV photon in highest gain range.
