Results of the Bayesian-like mock analysis with CIGALE. The ‘true’ values (labelled ‘IN’) were used to build the mock catalogue and are shown on the x-axes, while the SED fitting outputs (labelled ‘OUT’) are shown on the y-axes. The one-to-one relation is indicated as a solid red line. This exercise ensures that the stellar ages and times since quenching obtained from our SED fitting method are well constrained with the data at hand.
