GALFIT recovery of host galaxy parameters for the simulated AGN sample. a) Deviations between input host magnitude v_host,ini and recovered host magnitude v_{host,   sim} as a function of the deviations between input Sérsic index n_ini and recovered Sérsic index n_sim. b) Deviations between input H/N_ini and the recovered H/N_sim as a function of the deviations between original host magnitude and recovered host magnitude. c) Deviations between input H/N_ini and the recovered H/N_sim as a function of input H/N. d) Deviations between input H/N_ini and the recovered H/N_sim as a function of input host magnitude.
