Corner plot of the DIB fitting in the voxel with I_pix = 10450 and d_c = 1.05 kpc (the first panel in Fig. 7 from top to bottom). The histograms and scatter plots show the one- and two-dimensional projections of the posterior distributions of the fitted parameters. The red squares and lines indicate the best-fit estimates for each parameter in the reproduced fitting. And the dashed blue lines mark the fitted parameters in the output table of DIB-Spec.
