WebDec 10, 2024 · The Derived Count Rate (DCR) takes the actual attenuation level selection into account and represents the theoretical count rate at 100% laser power. WebWithin one orbit's table, each row will represent the derived count rate from one SRU image. The count rate values are derived from one of the two measurement techniques described in the SIS, indicated by a valid value in either column 4 or 5. The measurement technique will be chosen based on the overall radiation-induced noise level of that image.
