Mass-size plane for the galaxies from the sample in this paper (the red symbols) compared to the full sample from Serra et al. (2012). Data are taken from Cappellari et al. (2013b) while the definition of the H i classes is very similar to the one used by Serra et al. (2012): D: large H i disk (larger than optical body), R large H i ring (larger than optical body), d: small H i disk (confined within optical body), u: unsettled (tails, streams), c: scattered H i clouds. The blue, dashed lines give loci of constant velocity dispersion.
