Profiles (upper part of each panel) and residuals (lower part of each panel) of the brightness ($\mathcal{N}$; upper left panel), temperature (T; upper central panel), SZ-derived thermal pressure (P_SZ; upper right panel), redshift (z_u; lower left panel), and LOS nonthermal velocity dispersion (σ_v; lower right panel). The observational measurements are the black dots with the horizontal and vertical error bars indicating the bin extents and the 1σ statistical errors, σ_stat, respectively. The cyan vertical error bars indicate the total errors, $\sqrt{1+{ϵ}^2}{\sigma }_{\mathrm{stat}}$ (see Sect. 4.1, for details). The corresponding median values computed from the model and the corresponding median measurements from the mock spectra (see Sect. 5, for details) are the dashed blue and red lines, respectively, while the shaded rectangles span vertically the 16th–84th percentile intervals of the mock measurements. Both the uncertainty in the parameter values from the posterior and the Poisson noise in the mock spectra contribute to the error of the mock measurements, which is estimated as follows. We started with 100 measurements of the quantity W_m extracted from each mock spectrum. We randomly generated 100 values for each mock measurement according to the corresponding error. From the distribution consisting of all the values generated for every mock datum at a given bin, we measured the 16th–84th percentile interval.
