Mass-insolation diagram for small RV planets based on the planetary systems composite data table of the exoplanetarchive.ipac.caltech.edu/ (visited on 28 August 2020). Planets orbiting stars with temperature T_eff < 4000 K are displayed in orange colour, while the rest is plotted as grey circles. Planets with a dynamical mass measurement are shown as circles and planets with only a minimum mass (M sin i) measurement with boxes. GJ 3473 b and c are marked with red and blue diamonds.
