Figure 8
The pixel dark signal as measured at the SQS beamline during the first user operation period in 1/16 gain mode. The dark map is calculated from 400 dark frames as described in the text. The orientation of the image is the same as illustrated in Fig. 4, i.e. the photon signal is shifted and read out towards the CAMEX ASICs located on the left and right side of the sensor. The top and bottom histograms show the offset averaged along the CCD lines (top) and columns (right). |
