Distribution of the distance from the M(H2) vs. Mstar relations Δ(y) plotted in Figs. 2 and 3 determined assuming a constant XCO factor (panel a)) or the luminosity-dependent XCO factor given in Boselli et al. (2002) (panel b)). Negative values are for galaxies below the fitted relation. The black empty histogram gives the distribution of galaxies with Hi − def ≤ 0.3, the filled grey histogram that of the most Hi-deficient objects of the sample (Hi − def > 0.6). Non-detected galaxies are included at their upper limits. The red empty histogram shows the distribution of the spiral galaxies mapped in CO by Kuno et al. (2007) with Hi − def ≤ 0.4, the blue dashed histogram that of the Hi-deficient galaxies (Hi − def > 0.4). The black dotted and red dashed vertical lines give the one-sigma dispersion in the distribution determined for the whole sample of Hi-normal (Hi − def ≤ 0.4) galaxies (black) and for the subsample of objects mapped by Kuno et al. (2007; red). σ indicates the mean dispersion of the different distributions of unperturbed galaxies. KS indicates the probability that the two galaxy populations are driven by the same parent population (Kolmogorov-Smirnov test).
