Cornerplot of the posterior distribution. On the diagonal, the marginalised posterior distribution for each parameter of the model is plotted. The vertical lines represent the 16th and 84th percentiles of these distributions. The numerical values are reported in Table 1. The prior distribution is plotted in orange as a comparison: for the jump in the residuals Δr₀ and the magnetospheric time t_M this is almost invisible, due to the width of the distribution. The covariance plots are located off-diagonal.
