Notes. The galaxy coordinates are from Cappellari et al. (2011a). The morphological type is from de Vaucouleurs et al. (1991). NGC 3626 hosts a bar and has been reclassified as SAB0/a by Buta et al. (2015). The galaxy distance D is from Lelli et al. (2017). The K-band absolute magnitude MK (corrected for foreground galactic extinction), the atomic gas mass MHI, and the molecular gas mass MH2 are from Cappellari et al. (2011a), Serra et al. (2012) and Alatalo et al. (2013), respectively, and converted to the adopted distances. The HI mass of NGC 2824 is estimated in this work using deeper observations. The luminosity at 3.6 μm, the effective radius Reff encompassing half the total luminosity, and the effective surface brightness Σeff are from Lelli et al. (2017).
