For each of the 8 simulated clusters, we show the mean ratio between the radial values of δT_3D/T_3D and δn/n (red points), δT_2D/T_2D and in three different projections (blue diamonds), and the latter values corrected by the factor of 2 from Schuecker et al. (2004; the green squares represent the average values while the error bars represent the minimum and maximum values from the different projections).
