Fig. 8.


Projections of the 4D posterior distribution for the model parameters: slope (a), evolution (c), normalisation (b) and intrinsic scatter (σintr). The histograms on top show the marginalised distributions of the model parameters. The bias-corrected posterior median value and the 16th and 84th percentile are denoted by the dashed lines and by the values above the histograms. The contours show the 0.5, 1, 1.5 and 2σ levels. The posterior directly from the modelling is shown in black, red indicates the posterior after applying the bias correction (Eq. (A.3)). Figure created using the module (Foreman-Mackey 2016).
