Rest-frame turnover frequency versus linear size for our sources and those described in Appendix A. Red circles represent our sources while black squares represent sources from prior literature listed in Table A.1. The solid line represents Eq. (5), the dashed line represents the similar relation found by Orienti & Dallacasa (2014), arrows indicate maximum linear sizes for unresolved sources, and black circles indicate sources with unknown redshifts (set to 1 for this plot). For sources with unknown redshifts, colored lines are included to demonstrate the redshift dependence, with z specified by the color-bar.
