Results for the most relaxed/disturbed clusters and for the most smooth/irregular profiles with IAE for the 3D-3D fit. Left panel: Dashed cyan and magenta lines show the true 3D temperature profiles of the most relaxed and disturbed clusters respectively in the validation sample. Similarly, dashed green and orange lines show the most smooth and irregular true 3D temperature profiles respectively. The solid lines and the corresponding shaded regions show the median and 1-σ dispersion of the reconstructed temperature profile obtained from the IAE model using MCMC.
