Comparison plots of the different spectral parameters of the Centaurus cluster constrained from eRASS:5 spectra. The spectra were fit using different absorption values, as discussed in Sect. 3.4. The y-axes represent values obtained using the neutral hydrogen column density (N_HI), while the x-axes from the total hydrogen column density (N_Htot). Gray dashed lines indicate the 1:1 ratio, and the orange dashed lines represent offset lines, as detailed in the legends.
