Same as Figure 3, but for the five galaxies that have emission extended over greater than two beams but show no signs of coherent rotation. Here the lack of a rotational gradient implies that the velocity dispersion does not increase in the center owing to the effects of beam smearing. This is observed in both the data and the model, which again indicates that at this resolution the data are well modeled by a velocity dispersion that is constant throughout the [C II]-emitting region.
