NGC 1566 data and derived maps. Details are the same as in Fig. 1. With the spatial maps, we display the limit of the nuclear disc measured considering the peak in the V/σ radial profile, in a black solid ellipse. We find a nuclear disc with a radius size of 77 pc. Within the limits of the ellipse, we can notice most of the properties expected for a nuclear disc: increase in stellar velocity, decrease in stellar velocity dispersion, anti-correlation between h₃ and the stellar velocity, increase in h₄, decrease in mean ages, and decrease in [α/Fe]. The only property that differs from expected is the [M/H], which also decreases. This behaviour can be related to the original properties of the in-falling gas. Lastly, we mask the central region which presented strong emission lines, characteristic of AGN.
