Color–magnitude diagrams in the (BPgaia − DDO51) versus DDO51 plane. (a) Full sources with good quality and well matched with gaia. (b) Subsample of sources matched to the REGALADE galaxy catalog, with galaxy=True illustrating the locus occupied by galaxies. (c) Stellar sample obtained after removing the REGALADE-identified galaxies from the full catalog, yielding a cleaned stellar sequence. In all panels, the color scale indicates the logarithm of the number density of sources per bin.
