Comparison of two methods for determining the degree of rotational support in our sample plotted against the goodness of fit in the disk model. ﹩{v}_{c}/\sigma ﹩ from our disk fits and ﹩{\rm{\Delta }}V/2\sigma ﹩ from the peak-to-peak method is considered in the context of the reduced ﹩{\chi }^{2}﹩. Horizontal dashed lines represent the usually adopted thresholds, ﹩{\rm{\Delta }}V/2\sigma \geqslant 0.4﹩ and ﹩{v}_{c}/\sigma \gt 1﹩, for rotationally supported systems and the vertical dashed line represents ﹩{\chi }^{2}=20﹩, below which we consider the disk model to be appropriate. Without adequate sampling, a larger fraction of our sample would be incorrectly considered to be rotationally supported.
