Ratio of bulk velocity to dispersion as a function of the ellipticity, i.e., 1−D_min/D_max, where D_min and D_max are the size of the emission line gas along the minor and major axis, respectively. We show all 25 galaxies with emission line regions that are resolved along the major and minor axis, and have well defined ratios of v/σ. The green dotted area shows the region occupied by the fast rotators in the ATLAS^3D survey (Emsellem et al. 2011). The red line delimits the range in parameter space for slow rotators. See Emsellem et al. (2011) for details of the physical properties of these two regions.
