Calculated corrected color excesses (C*) based on M. Riello et al. (2021), in order to evaluate the Gaia DR3 G_BP and G_RP photometry against G. The dark blue points are stars from panel (c) of Figure A1. Overmarks in light pink and dark red represent RGB and EAGB stars, respectively. Dashed blue lines correspond to the 7σ scatter, while the solid red curves are for 10σ, see more information in Appendix A. This figure confirms the nature and positions of our sample stars, with a particular regard for EAGB10, EAGB11, and RGB27.
