Photometric errors derived from the artificial star tests. The panels show the difference between output and input magnitudes as a function of the output magnitude (left panels: F814W-band; right panels: F606W-band). The vertical gray line indicates the magnitude corresponding to the 50% completeness factors, while the gray error bars show the mean magnitude difference as a function of the output magnitude.

CMDs of stars within three selected elliptical radius annuli. The limits of the annuli are indicated within each panel. In the first annulus (upper panels) we overplot Padova isochrones, shown in black, of a range in ages, and with Z metallicity of 0.001, as detailed in Sect. 3.3.
