Two-dimensional correlation distributions of the TBabs*vnei part of the model for region 1 of the SNR G53.41+0.03. Posterior distributions of individualparameters are described by the median and the 1σ confidence interval. Contours in the two-dimensional histogram represent 0.5, 1, 1.5, and 2σ levels. Instrumental line components are not displayed for readability reasons. Full version of the figure, including the instrumental line components, is available in the zenodo archive.
