Radii of M and K dwarfs as a function of their masses. The gray dots correspond to the measurements obtained by Parsons et al. (2018) by compiling catalogs and observing new targets. Among the values presented by these authors, only those with a relative uncertainty less than 10% are shown. We note that the uncertainty on the radius (resp. mass) of the companion of KIC 4360072 (resp. KIC 10074700) is greater than 10%. We however decided to keep them on the plot to allow for comparison with the most up-to-date scatterplot.
