Notes. The sources AzTEC/C1b, C8b, C10c, and C13b were not detected in our ALMA 870 μm survey, while AzTEC/C3b was not covered by our ALMA pointings (see Sect. 2).

(a)

Deconvolved FWHM of the major and minor axes derived through Gaussian fits in the image plane using the AIPS task JMFIT.

(b)

Major axis position angle of the fitted Gaussian measured from north through east. Formally, the PA lies in the range PA ∈ [0°, 180°], but some of the tabulated values have uncertainties that place the PA value being outside this range. However, the PA is symmetrical under a 180° rotation.

(c)

Spectroscopic redshift (see Brisbin et al. 2017, and references therein).

(d)

No MAGPHYS SED could be derived for the source, while AzTEC/C11 and C24b were excluded from the SED analysis because they are likely to host an active nucleus (M17b).
