Bar chart showing the differences of the log-evidences of the 21 tested models, which are labelled on the X axis. The grey, blue, green, and red bars represent models with zero, one, two, and three planets, respectively. The vertical magenta shade highlights the simplest model that best represents our data set (2plc2cQ). The horizontal grey shade indicates the 0 ≥ Δ ln (𝒵) ≥ –6 region from the model with the largest evidence.
