Recovery of forward modelled parameters as a function of redshift and luminosity using maximum likelihood. The plots show the recovered parameter values as a function of redshift, for clusters with an input shape compared to an input spherical cluster. The error bar shows the average best fitting parameter and the uncertainty on the mean. The shaded region shows the 1σ range of the recovered best fitting parameters. The panels show shaped models with ϵ = 0.7, H = 0.3, M₁ = 0.3, M₂ = 0.3, M₃ = 0.3, and M₄ = 0.3, respectively, compared to the spherical models.
