Notes.
Distance is the median values of z-independent distances from NED Steer et al. (2017).
The RA-Dec positions are the new adopted center, derived from the central continuum peak in this work, with an uncertainty of ∼0.1″ (see Sect. 3.1).
The RA-Dec positions of the nuclear spiral, used as the kinematical center in Sects. 3.4 and 4.6.
