1D posterior distributions and 2D confidence (68% and 95%) contours for the parameters A_TM, Ω_m, and σ₈, as derived from our MCMC analysis in three different cases: contraints from CMB+clusters using either the SMT mass function (red), the Tinker mass function with a virial mass definition (blue) or with M₅₀₀ critical masses (black). The statistical analysis of the corresponding MCMC chains is given in Table 2.
