Comparison between the profile derived with the direct spectral fitting of each annulus j (i.e., T_spec, j). and the temperatures recovered from the maps using Eq. (2) (i.e., T_1D, j) in the same spatial regions. Each blue point corresponds to an annulus of the 28 clusters, while the black points represents the average values with the shadow area including the 16th and 84th percentiles.
