Radius vs. equilibrium temperature diagram: known planets with a precision of 10% or better in radius are plotted in grey. About a third of these planets have also RV mass measurements with a precision of 30% or better and are colour-coded with planet mass. We set upper limits to planet masses at 13 M_J. TOI-2196 b is marked with a red star symbol, the five additional planets in the hot Neptune desert with black diamonds, and solar system planets with brown squares. The five additional planets located in the desert are: K2-100 b (Barragán et al. 2019a), TOI-849 b (Armstrong et al. 2020), LTT 9779 b (Jenkins et al. 2020b), K2-278 b (Livingston et al. 2018), and Kepler-644 b (Berger et al. 2018) of which the latter two have only radius measurements.
