Notes. The error on M_500,X is mainly the uncertainty of the X-ray luminosity mass relation. The T_X of the A76 cluster corresponds to the value provided by Ota et al. (2013). For more precise values on the temperature see the temperature profile of A76 in this paper. For precise values of the temperature profile of A1307 see the profile in Fig. 8. The SZ mass, M_500,SZ, has been retrieved from PSZ2 Planck catalogue.
