Notes. The positions of the extracted regions are given relative to that of the nucleus of the galaxy. All the reported values of EW(Hα)em are in emission. The values of HδA are not corrected for Hδ nebular emission.

†

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