Magnitude distributions of OGLE4 eclipsing binaries that have a GaiaG magnitude. The distributions are given for the LMC (top panel), the SMC (middle panel), and the Galactic bulge (bottom panel). The OGLE4 I and V magnitudes are shown with a thin green and a dashed grey line, respectively, and their GaiaG magnitude is shown with a thick red line. The G distribution of the subset present in the Gaia catalogue of eclipsing binaries is shown by the filled blue histogram.
