Pedestal performance for the three different gain modes: low gain (top), medium gain (middle) and high gain (bottom). (a) Average pedestal taken 15 min after a pedestal was recorded and applied. (b) Similar pedestal after CM correction. (c) Standard deviation of the recorded pedestal shots. (d) Standard deviation after CM subtraction. (e) Absolute mean of the CM in the individual banks mapped onto the detector. |
