Results of the z = 2 mock catalog analysis for the two parameters age_trunc and r_SFR. The five left panels present the constraint on age_trunc for five different τ_main (1, 3, 5, 7, and 10 Gyr). The colored lines corresponds to different values of r_SFR. The five righthand panels display the constraint on r_SFR for the same five values of τ_main (1, 3, 5, 7, and 10 Gyr), the colored lines corresponding to different age_trunc. On each panel, the black solid line is the one-to-one relationship.
