H I mass and size scaling relation. The green dots represent ∼500 nearby galaxies analyzed by Wang et al. (2016). The solid black line shows the best fit of Wang et al. (2016)’s sample, and grey colors show its 3σ and 6σ scatters. The errorbars of D_HI and M_HI measurements are plotted. The red diamonds represent the sample for this study. Most of our targets follow the scaling relation within a 3σ scatter and are clustered in the high M_HI–D_HI regime. The objects that deviate most significantly from the rest of our sample are labeled with their BAT IDs.
