Distribution of K_p values fitted on randomly generated planetary RV curves with properties described in the text. The vertical black solid line represents the median value of the distribution, while the 2 vertical black dashed lines represent the 2 quantile values delimiting the 68% (1 σ) interval of K_p around the median. The vertical dash-dotted blue line represents the expected K_p value: ${\hat{K}}_{\mathrm{p}}$ = 123.4 km s⁻¹. The median and the expected values are coincident and therefore they are not visibly distinguishable.
