Corner plot for the left panel fit shown in Figure 4. Shown are one- and two-dimensional projections of the sampled posterior probability distributions, referred to as marginalized and joint distributions, respectively, of the nine parameters for the fit. Contours in the joint distributions are shown at 0.5σ, 1σ, 1.5σ, and 2σ, and the histograms’ dashed black vertical lines show the 16th, 50th, and 84th percentiles of the samples in each marginalized distribution. Text above each histogram shows the median ± the 68% confidence interval.
