Notes.

^(a)

The gas masses used to derive these gas surface densities were estimated using the Scoville et al. (2016) dust continuum method, which is based on the assumption of a uniform, Galactic α_CO conversion factor.

^(b)

The MS definition was adopted from Speagle et al. (2014).

^(c)

The starbursts were defined as objects that lie above the MS mid-line by a factor of > 3.
