Specific merger mass accretion rate (in units of Gyr-1) as a function of the stellar mass ratio of mergers, for z = 0. The lines are exactly the same as in Fig. 1 but now we use the measured mean Hi-to-stellar mass ratio as a function of stellar mass from a reference sample of local galaxies with normal sSFR from Papastergis et al. (2012), and sSFR = 0.08 Gyr-1. We also indicate the determinations of the Hi accretion rate from two surveys of local spirals (Sancisi et al. 2008; Di Teodoro & Fraternali 2014, gray-shaded region and dashed lines respectively; see text for details).
