Correlation diagrams for the probability distributions of the updated reloaded RM model parameters. Samples have been limited to the region with low stellar inclination. The inner green and outer light blue contours show the 1 and 2σ simultaneous 2D confidence regions that contain 39.3 and 86.5% of the samples, respectively. 1D histograms correspond to the distributions projected on the space of each line parameter. The deep blue lines indicate their median values, with dashed green lines showing the 1σ highest density intervals. ψ is derived from other parameters and is not an MCMC jump parameter.
