Distribution of sources in the residual overdensities marked in red and blue in the lower-right panel of Fig. 15 in the CAMD diagram of (G − J) and M_G. It shows the main sequence derived from the GCNS as black dots (using transparency); the list of sources in our catalogue of UCDs in HMAC groups of fewer than ten members (salmon dots with transparency); the GUCDS (violet dots); and the position of the sources in the blue and red overdensities after de-reddening using the Planck GNILC (Planck Collaboration XLVIII2016) dust map as orange and green dots, respectively.
