Notes. Column three gives the input values to create the S1 and S2 realistic simulations, Column four gives the ranges that are explored during the MCMC analysis. Column five to seven give the best-fit parameter values and the corresponding 1σ MCMC uncertainties obtained for the cases A, B, and C, described in Sect. 5.
