Mean likelihoods, computed over the whole chains, for binned parameter values (dotted lines) and marginalized distributions (black lines) of some parameters of interest for an artificial galaxy of the mock sample considered; the blue vertical lines show the input parameter values used. Poorly constrained parameters, such as τ ₁, t ₂, f _ySP, f _V , and α, are clearly visible. Luminosities and masses are in units of solar luminosities and solar masses, respectively.
