Recovered parameter bias from simulated clusters as a function of the redshift and number of counts inside an 800 kpc radius circle. For the concentration, central density and cuspiness, shown is the difference between the recovered values and the input profile, after deprojecting the emissivity profile. For the shape parameters, ϵ, H and M₁ to M₄, we show the difference between the recovered and input values (0.7 for ϵ and 0.3 for the others), for simulations with non-spherical clusters. For the parameters w, A_phot and P₁₀ to P₄₀, we show the value for a spherical cluster.
