The z_spec and z_phot values are the spectroscopic redshift and optical-NIR photometric redshift, respectively.

AzTEC11 was resolved into two 890 μm sources (N and S) by Younger et al. (2009). The two components are probably physically related, i.e. are at the same redshift (Miettinen et al. 2015). In the present paper, we adopt AzTEC11-N as the target SMG.

The SMG has two components with a projected angular separation of , and they lie at the same z_spec (A. Karim et al., in prep.).

The AK03 SMG is also composed of two components (N and S) whose angular separation is ~ in the optical. The z_spec = 4.747 refers to the northern component, and the southern component has a comparable z_phot of (4.40 ± 0.10) or (4.65 ± 0.10), depending on the template set used (Smolčić et al. 2015).

The coordinates given in Cols. (2) and (3) for AzTEC1–15 refer to the SMA 890 μm peak position (Younger et al. 2007, 2009), while those for AzTEC17–29 are the PdBI 1.3 mm peak positions (Miettinen et al. 2015). For J1000+0234 the coordinates refer to the PdBI-detected ¹²CO(4–3) line emission peak (Schinnerer et al. 2008), while those for AzTEC/C159, Vd-17871, and AK03 refer to the VLA 3 GHz peak position (Smolčić et al. 2015), and that for Cosbo-3 from the CARMA peak position (Smolčić et al. 2012b). The redshift references in the last column are as follows: 1 = Yun et al. (2015); 2 = E. Faustino Jimenez Andrade et al. (in prep.); 3 = Riechers et al. (2010) and Capak et al. (2011); 4 = Smolčić et al. (2012a); 5 = Miettinen et al. (2015); 6 = D. A. Riechers et al. (in prep.); 7 = M. Salvato et al. (in prep.); 8 = Capak et al. (2008) and Schinnerer et al. (2008); 9 = Smolčić et al. (2015); 10 = A. Karim et al. (in prep.).
