Distributions of surface gravity and mean radius of APOGEE DR17 flag selected stars. The log g normalised histogram is shown at the top. The dashed vertical lines represent the thresholds chosen to select stars in three log g intervals (red giants: log g < 2.2, in orange; red clump stars: 2.2 < log g < 2.7, in purple; dwarfs: 3.5 < log g < 4.45, in green). The mean orbital radii density histogram of the selected stars separated into the three log g intervals is shown at the bottom, with the same legend as in the top panel.
