Corner plot showing marginalised one-dimensional and 2-dimensional posterior probability densities on the SN model parameters obtained by fitting the SN 2019wxt photometric dataset. The red lines and square markers show the estimated position of the maximum a posteriori. Dashed lines in the plots on the diagonal bracket 90% credible ranges. Contours in the two-dimensional plots show credible regions at the 68%, 95% and 99.7% credible level, while black dots are random samples from the posterior, qualitatively showing the behaviour outside the contours. The physical meaning of the parameters is described in the text.
