Appendix A: global properties of the main galaxies

In this Appendix, we list the main properties of the spiral galaxies selected from the WHISP sample for this work. Columns are as follows:

Column (1) gives the UGC name.

Column (2) provides an alternative common name, such as NGC, DDO, or IC classifications.

Column (3) provides the adopted distance in Mpc. We preferably used the EDD catalogue (Tully et al. 2009), otherwise, we used the following distance sources, in the given order: Cosmicflows-2 (Tully et al. 2013), NED archive, Hubble flow with H0 = 70 km s-1 Mpc-1 and systemic velocities corrected for Virgo-infall taken from the HyperLEDA catalogue.

Columns (4) and (5) give the radius R25, namely the length of the projected semi-major axis of a galaxy at the isophotal level 25 mag arcsec-2 in the B band. R25 is taken from the HyperLEDA catalogue. In Col. (4) the radius is listed in

arcminutes, in Col. (5) it is converted into kiloparsecs using the distances in Col. (3).

Column (6) provides the inclination angle derived from the axis ratio in B band as listed in the HyperLEDA catalogue.

Column (7) gives the systemic velocity measured in this work as the average midpoint between the velocities at the 20% and 50% of the peak flux of the global Hi-line profile.

Column (8) gives the Hi-line width at the 20% of the peak flux of the global Hi-line profile, as calculated in this work.

Column (9) provides the total Hi mass estimated in this work.

Column (10) gives the adopted total baryonic mass Mbar, calculated as described in Sect. 2.3.

Column (11) provides the star formation rate calculated from the 60 μm and 100 μm IRAS fluxes.

Column (12) gives the total gas accretion rate from minor mergers estimated in this work, including detectable and “hidden” accretion.
