Cornerplot of the fitted parameters (power-law normalization, photon index, column density, and background normalization) for the eROSITA observations. The histograms represent the individual parameter posterior distributions, while the shaded contours show the credibility regions of the interception of different parameters. The darker shades correspond to 68% of the integrated posterior, and the lighter shades to 90%. The color-coding is the same as in Fig. 11.
