Same as Fig. 7 but for the regular and irregular subsamples. Left figure: Bias in ICM density profile due to the spherical assumption. In the bottom panel, the zoom of the innermost region is reported. Right figure: Scatter profile of each sample’s density profiles around the global density profile (upper panel) and the relative bias due to the spherical assumption (bottom panel). The black lines refer to the complete sample, the red lines to the irregular sample, and the blue lines to the regular sample. The lighter lines refer to the global density profile for each sample realization (one for each line of sight), the solid lines to the mean over the sample realizations, and the dash-dotted lines to a 1σ value. In the right figure, the dashed lines refer to the input profile; the green dashed line refers to the 50% level.
