Notes.

Integrated spectra refers to the central ~5 kpc to ~8 kpc regions, depending on the galaxy (see Paper I for details). All the reported values of EW(Hα)_em are for the line observed in emission.

The values of Hδ_A are not corrected for Hδ nebular emission.

^†

The nebular Hδ line is clearly seen in emission within the stellar absorption feature.
