Two-dimensional distribution of the standardized error as a function of the target mass. The black line marks the median of each distribution at a fixed target mass while the dashed lines mark respectively the 16th and 84th percentiles. The graph shows a distribution in fine agreement with the expected one for planets of masses approximately between 10 M_⊕ and 6 M_J (assuming M_★ = 1 M_⊙). Lower and higher masses are instead, respectively, systematically overestimated or underestimated.
