Reference. Hubble stage T is from Tully (1988); galaxy morphology (RC3 type) and redshift-independent distances (Dist.) are from NED database; D25 is from HyperLeda database; sub-mm diameter (Dsub−mm) and sub-mm minor-to-major axis ratio ((d/D)sub−mm) have been measured in the present work. Coordinates (αJ2000, δJ2000), inclination angle (i), position angle (PA), and minor-to-major axis ratio (b/a) are from: 1) Walter et al. (2008) (THINGS), 2) Westmeier et al. (2011), 3) NED, 4) Jorsater & van Moorsel (1995), 5) de Blok et al. (2008), 6) Crosthwaite et al. (2000), 7) Leroy et al. (2012), 8) Ondrechen et al. (1989). a Classification of nuclear activity is from NED: H = H ii nucleus, S = Seyfert nucleus, and L = LINER. The number attached to the class letter designates the Seyfert type, classification based on the appearance of the optical spectrum (Osterbrock 1981). Two classifications are given for some ambiguous cases.
