Notes. From left to right, the columns represent region number (GMC), mean deviation from the model to the observed data (adev), total luminosity (Lumtot), stellar mass (M⋆), velocity offset (v0), stellar velocity dispersion (σ★), attenuation at V band (AV), extra extinction applied to young stellar populations (δAV), percentage of stellar populations affected by the extra extinction (x(δAV > 0)), the effective extinction (
), which is equivalent to AV + δAV × x(δAV > 0) and corresponds to the total extinction; the mean light-pondered ages (⟨log t⋆⟩L), mean logarithmic mass-pondered ages (⟨logt⋆⟩M), mean logarithmic light-pondered metallicity (⟨log Z/Z⊙⟩L), and mean logarithmic mass-pondered metallicity (⟨log Z/Z⊙⟩M). Further information is provided in Sect. 4.2.
