Bolometric luminosity (Lbol), Eddington ratio (λEdd), star formation rate (SFR), and stellar mass (M*) as a function of the relative extent of H I gas including low-density gas (DHI, ext) to stellar disk (D25). Lbol and λEdd are adopted from BASS DR2 (Koss et al. 2022a). Each galaxy is colored by the hard X-ray luminosity adopted from Ricci et al. (2017). On each panel, the Spearman rank correlation (S) and the Pearson correlation (P) coefficient, and a p-value between each axis are shown at the bottom. There is a marginal, linear correlation between Lbol and the H I extent in the sense that galaxies with a relatively larger H I disk compared to the stellar disk are more luminous. This also applies to the Eddington ratio, whereas the relative size of H I does not seem to be related to SFR. M* appears to show a marginal negative correlation with DHI, ext/D25, which is naturally expected, as DHI, ext is normalized by D25.
