Top: angular FWHM of the major axis at 3 GHz as a function of the 3 GHz flux density. Bottom: same as above but as a function of the 890 μm flux density. For AzTEC17a, 19a, 21a, 24b, and 27 the value of S_{890 μm} was calculated from S_{1.3 mm} by assuming that the dust emissivity index is β = 1.5; these data points are highlighted by red filled circles in both panels. The horizontal dashed line marks the median major axis FWHM of . The upper size limit for AzTEC3 is indicated by a downward pointing arrow.
