Notes.
Test scans that were performed before the official start of the survey between 2019 Decenber 8 and 2019 December 11 are designated as eRASS0.
Net exposure after correcting for vignetting and normalised to seven telescope modules. The lower exposure in epoch 4 arises because only four cameras were active (TM1, 2, 3, and 6) for most of the epoch.
Variability Var of the light curve within the given epoch and significance S of the stated variability. For the parameter definitions, see Sect. 3.2.
