Mass-weighted histograms of the density, temperature, and instantaneous thermalized heating rate obtained from the BLh runs using the in situ NN (ThK-S_BLh) or the analytical fits for the nuclear power (Apr2_BLh). The top and bottom groups of plots show the ejecta at early (pre neutron freeze-out) and late (t ≃ 10 days) times. The left [right] column shows the profiles as functions of the polar angle [initial electron fraction]. The gray lines in the heating rate panels separate negative and positive values.
