F-measure evolution as a function of the H_E magnitude in each of the regions shown in Table 6, computed in the 7 < z < 8 interval. Two cases are shown for the contribution of MLT stars. In yellow is presented the evolution when only the thin disc contribution is accounted for, both in the simulation and the Bayesian modelling. In blue, the same result is shown when the contribution of the thick disc is added to the simulations.
