Sample of posterior distributions (grey histograms) for the Doppler semi-amplitude Kd of planet K2-3 d obtained from the GP regression analysis of the mock RV datasets described in Sect. 5.1. Each plot shows the marginal distribution for a single mock dataset, and this is compared to the posterior distribution obtained forthe real TERRA RV dataset, represented by the yellow histogram. The vertical dashed lines indicate the 50th (green) and 68.3th (black) percentiles for the posterior distributions of the mock datasets.
