Mode of the error distribution on the weighted mean G–band magnitude as a functionof G magnitude for (1) the uncalibrated source photometry (Raw), (2) the source photometry obtained after the first LS solution in the calibration intialisation loop described in Sect. 5.1 (LS1), and (3) the source photometry obtained after the last SS+LS iteration. The increased scatter at G ≤ 13 is related to changes in the observation configuration (e.g. window class/gates), the limitations in the IPD algorithms,and the handling of saturation and flux loss. A more in-depth discussion can be found in Evans et al. (2017, 2018).
