Density distributions of the total stellar mass M_⋆ in solar units M_⊙ (left-hand side panels), mean stellar age ⟨log t_⋆⟩ in years (centred panels) and mean stellar metallicity log⟨Z_⋆⟩ in solar units (right-hand side panels). Blue and red colours represent results from FADO and STARLIGHT, respectively, for the passive sample (darker colours) and intensively star-forming sample (lighter colours). Other legend details are identical to those in Fig. 4.
