Plot of the radius of the primary as a function of the separation intervals normalised with the Roche limit for fluid satellites, for the sample of 156 asteroids with known taxonomy. The squares represent the mean value of the first mass ratio interval estimated and the circles represent the second interval. The coloured symbols with dark borders are the objects from the taxonomic filtering with $\widehat{S/N}>1$, and the grey symbols are those with $\widehat{S/N}<1$.
