Mass-weighted mean stellar age distribution with present-day stellar mass, as obtained by STARLIGHT, FADO and FADO_ST. The left-hand side panel compares the aforementioned distribution as obtained by STARLIGHT and FADO_ST, whereas the middle panel compares the same as obtained for FADO and FADO_ST. The two right-hand side panels demonstrate how the normalised difference between the estimated stellar mass and mass-weighted stellar age (considering and ignoring the nebular contribution) relates to the logarithm of the flux associated with the sum of all emission lines, log₁₀F_Σ(emission), in units of 10⁻¹⁶ erg cm⁻² s, which is a direct proxy for the nebular continuum level. Linear regressions to the respective data points are overlaid.
