Example of an AstroPhot fitting process on VIS data to derive photometric and morphological properties. Left: Input image (4000 pixel × 4000 pixel pixel cutout, 400″ × 400″) featuring multiple overlapping galaxies from the Perseus cluster, namely NGC 1270, NGC 1268, NGC 1267, and CGCG540-089. Centre: Segmentation map of the image by SourceExtractor (scale in pixels). Right: Residual image (image minus models) for the initial fit, this gets substantially improved upon iterating.
