Extinction-corrected Gaia CMD of the 273 sources (filled red circles) with G_BP − G_RP on the x-axis and M_G on the y-axis is shown in the top panel. The vertical black line that divides the CMD into two populations, is at G_BP − G_RP = 0.4. The black arrow shows the reddening vector for A_V = 1 mag. The Number distribution of the 273 sources in the G_BP − G_RP colour is shown in the bottom panel
