Notes. Region Nuc corresponds to the nucleus of NGC 4569. Start and End denote the position in arcseconds with respect to the photometric centre where the 1D extraction is performed. log (Hα/Hαnuc) is the brightness of the Hα line in a given region normalised to that of the nucleus. ΔV is given with respect to the systemic velocity of NGC 4569 (−221 km s-1).
