Analysis of the difference between Gaia's photometric (color-based) absolute magnitudes and photometric magnitudes derived from SDSS colors. Symbols show a sample of 165,834 stars with absolute magnitude Mr,Pho > 4, and SDSS-based u < 21 and 0.2 < g − r < 0.6. The median magnitude difference is −0.05 mag, with a scatter of 0.32 mag. The four panels illustrate the variation of the binned median (red circles) and scatter (red lines) with the u-band magnitude, SDSS u − g and g − r colors, and photometric metallicity.
