Total mass biases estimated with different approaches, HE (black), FGF (red), SL (blue), for three representative clusters of our sample (from top to bottom: Cl_A1689, Cl_A2204, and Cl_{RXJ1347.5−1145}). The ISO parameters used for the bias estimation are associated to SZ signals convolved with a beam of 7 arcmin (FWHM). In panel a) the total mass bias is shown, while in panel b) the reliability of bias estimation has been tested. The two bias contributions are disentangled: integration c) and modeling d) biases. Assuming no prior for T_e, the mass biases are plotted versus a reliable range of electron temperatures (5–15 keV).
