Fig. A.3.


Comparison of the surface brightness profiles of the spiral galaxy ABYSS-1 (α = 53.16993, δ = −27.77106, Elmegreen et al. 2005) for the F105W (top left panel), F125W (top right panel), F140W (bottom left panel), and F160W filters (bottom right panel), using our own reduction of the HUDF WFC3 mosaics (ABYSS, black dots), the HUDF12 (Koekemoer et al. 2012, blue squares), and the XDF (Illingworth et al. 2013, red triangles). The top plot of each panel shows the surface brightness profile for each reduction. Black solid, blue dashed, and red dotted lines represent the elliptic aperture with largest semi-major axis that presents an S/N higher than 3 over the sky-level. The bottom plot represents the difference in magnitude of each previous reduction with the ABYSS version of the mosaics as a function of galactocentric radius. Consult the legend on the figure.
