Histograms from the posterior distribution samples of TOI-1273 b (radius, mass, and density from top to bottom). The error bars represent the reported value for each parameter, which is the median ±1σ. The red dashed line on the lower panel shows the value at which we put the prior constraint on the density. In the lower panel the bulk density distribution of confirmed planets with masses and radii determined to better than 20% precision is also shown.
