Notes. Main properties of the sample galaxies. The columns list the following: (1) Galaxy name; (2) Right ascension (αJ2000) and (3) Declination (δJ2000) in J2000 coordinates; (4) RC3 classification type; (5) Optical diameter; (6) Galaxy distance; (7) Galaxy inclination angle; (8) Nuclear activity. The galaxies are arranged in order of increasing distance. Distances are primarily taken from the Cosmicflows-3 database (Tully et al. 2016), except where noted otherwise:

(b)

Sabbi et al. (2018). The nuclear activity classification is from:

The nuclear activity is classified as HII, Seyfert, and LINER. Two galaxies (NGC 5236, NGC 3621) display ambiguous nuclear classifications.
