In light blue, MCMC 68% and 95% contours for the cosmological parameters and the halo mass function parameters for a Euclid-like catalog. We fixed α = 1. The dark blue contours are obtained when adding Planck priors. The dashed lines are the Gaussian fit from which the covariance matrix and subsequently the Fisher matrix Fclusters(α = 1) is computed.
