Absolute magnitude in the G band vs. G_BP − G_RP color diagram, corrected for dust reddening, of the 1 898 063 high-quality sources in common between Gaia DR3 and J-PLUS DR3. The color scale presents the number density of stars per mag², noted as ρ_⋆. Three areas were defined following López-Sanjuan et al. (2019) as being dominated by main sequence stars (white area), giant branch stars (gray area), and white dwarfs (blue area).
