Notes. The meaning of columns is as follows: (1): SMG name; (2) and (3): peak position of the fitted Gaussian; (4): peak surface brightness; (5): total flux density provided by the Gaussian fit; (6): S/N as determined from the maximum pixel value with respect to the rms map noise; (7) and (8): deconvolved FWHM size (θmaj × θmin) in arcsec and physical kpc; (9) position angle of the fitted Gaussian measured from north through east; (10): projected angular offset from the (sub)mm position.
Formal 1σ uncertainties in seconds for α2000.0 and arcseconds for δ2000.0 returned by JMFIT are given in parentheses.
The quoted error in I3 GHz is the 1σ rms noise in the map determined inside a ~300 Λ″ box placed near the SMG, and which did not include any 3 GHz sources. The uncertainty in S3 GHz represents the formal error determined with JMFIT. The uncertainties do not include the absolute calibration uncertainty.
The size and PA uncertainties represent the minimum/maximum values as returned by JMFIT. We note that the PA is formally defined to range from 0° to 180°, but for example for AzTEC2 the maximum PA value is 
, which is equivalent to an angle of 
. The minimum and maximum PA values for AzTEC8 and 24b are equal to the nominal value, and hence the quoted uncertainties are equal to zero.
Two 3 GHz sources were detected. No linear size is reported for the secondary component towards AzTEC2 because of its unknown redshift.
For AzTEC6, 24b, and 27 only a lower redshift limit is available (see Table 1), and the linear FWHM size quoted in parentheses was calculated at that lower z limit; these linear sizes were not included in the statistical size analysis.
