We calibrated the EndY photon calibrator today. We have started reporting the final calibration factors in Newtons/Volt of PD readout as per our new calibration scheme detailed in alog # 20334. The new calibration factors compared to the the last calibration is tabulated below and is also uploaded to T1500252.
