Left: planets with measured M_p or ﹩{M}_{{\rm{p}}}\sin (i)﹩, using ﹩\sin (i)=\pi /4﹩. Planets with measured inclination (P1 sample) are colored according to discovery method: purple—Kepler, red—K2, green—TESS, black—radial velocity surveys, cyan—mostly ground-based photometric surveys. Circular points denote radial velocity derived masses, triangular points masses from transit timing variations. Points without measured inclination (P2 sample) are gray. The gap is shown by a dashed line. Right: histogram for our P2 (green) and P1 (purple) samples taken on the gradient of the dashed line, limited to planets within 20M_⊕. Bins are 3M_⊕ wide. Data points are shown with a random vertical distribution within the histogram bars.
