Top row: 2D fit maps of the five populations in IC 5052 (from left to right: RGB, AGB, lowHeB, upHeB, MS). Each panel contains three maps: top: stellar density maps, middle: best-fit model, bottom: weighted residual (data−model, see Eq. (C.1)). The gray lines show the regions from which the minor and major axis profiles are extracted. The two overdensities in the residual map of the fit to the RGB data (left panel). Bottom row (middle and right): major and minor axis profiles of the data (solid lines) and the 2D models (dashed lines); dotted vertical lines show the break radii. The model lines may show irregularities (as the real data do) due to masked-out regions.
