Analysis of the difference between Gaia's geometric (trigonometric) absolute magnitudes and the photometric magnitudes derived from SDSS colors. Symbols show a sample of 33,186 stars with a parallax signal-to-noise ratio above 10, absolute magnitude Mr,Geo > 4 and Mr,Pho > 4 , and SDSS-based u < 21 and 0.2 < g − r < 0.6. The median magnitude difference is −0.01 mag, with a scatter of 0.28 mag. The four panels illustrate variations of the binned median (red circles) and scatter (red lines) with the u-band magnitude, the parallax signal-to-noise ratio, SDSS g − r color, and photometric metallicity.
