M_G vs BP-RP CMD of the candidate members of the NYMG candidates before applying the r_c > 0.1 cut (grey dots), highlighting the sources that are discarded with this cut (red crosses). The dashed lines indicate the 100 Myr (blue line) and 1 Gyr (black line) isochrones. Top, middle, and bottom plots correspond, respectively, to the members according to the candidates of S _lit, the candidates of the detected groups from this work, and the exact match between the two latter samples.
