Notes. First parameter set: slope αsl, normalization, n0, and scatter of the LX − M relation, and scatter combined with the flux error. Second parameter set: H0, Hubble constant, Ωb baryon density, ns slope of the primordial power spectrum, Ωm + ΩΛ − 1, degree of the deviation from a flat universe, fmass mass bias, and w, equation-of-state parameter for Dark Energy assumed to be constant. P heading the columns indicates the parameter of the row. ΔΩm and Δσ8 give the change in the resulting values for these two parameters upon a parameter variation, ΔP.
