Correlation matrix between the median obtained shell-model parameters. The color coding denotes the “confidence” category the spectrum was assigned (blue = 1, green = 2, red = 3). While the lower triangle shows scatter plots with each spectrum marked individually, the same data is plotted as contours of kernel-density estimators in the upper right triangle. The panels along the diagonal show stacked histograms of the (projected) distribution.
