Notes. The different RV reduction schemes using APERO v6 and v7 are presented in Sect. 4. For all parameters, except those of GPs, the main value is the median and the uncertainty is the average distance of the median to the 16th and 84th percentiles. For the GP hyper-parameters, since the posteriors are asymmetrical, the main value is given by the mode, and the uncertainties are the distance between this mode and the 16th and 84th percentiles. (a)The ABIC is calculated between the model without any signal (planet or GP) and the model considered in the given column header.
