Left: F560W image with linear intensity scaling. Coloured patches show regions with different depths where we have estimated the noise (see Table 1): the deepest area (A), where Obs 1–2, 4–6 overlap (yellow). The deep area (B), where Obs 4 does not overlap fully with the others (green). Outside these areas, there is coverage at less depth, notably the NE extension which only has observations from Obs 4. The area with at least 7h of combined integration is denoted C (purple). The orientation is in the detector plane (x,y). Right: Exposure time map.
