Notes. z_spec is the redshift inferred from previous CO detection as reported by: (1) Riechers et al. (in prep.); (2) Lupu et al. (2012); (3) Fu et al. (2012); (4) Harris et al. (2012); (5) Harris et al. (in prep.); (6) Krips et al. (in prep.); (7) Cox et al. (2011). F₂₅₀, F₃₅₀ and F₅₀₀ are the Herschel SPIRE flux densities at 250, 350 and 500 μm, respectively (Valiante et al. 2016); F₈₈₀ is the 880 μm SMA flux density (Bu13); f_{1.4 GHz} is the 1.4 GHz band flux density from the VLA FIRST survey (Becker et al. 1995), and we use 3σ as upper limits for non-detections; T_d is the cold-dust temperature taken from Bu13 (note that the errors quoted here are underestimated since the uncertainties from differential lensing and single-temperature dust SED assumption were not fully considered). μL_IR is the apparent total infrared luminosity (8–1000 μm) mostly inferred from Bu13. μ₈₈₀ is the lensing magnification factor for the 880 μm images (Bu13); r_half and Σ_SFR are the intrinsic half-light radius at 880 μm and the lensing-corrected surface SFR density (SFR is derived from L_IR using the calibration of Kennicutt 1998a, SFR = 1.73 × 10^-10L_IRM_⊙ yr^-1, by assuming a Salpeter IMF); Since G12v2.890 and G12v2.257 are significantly weaker in submm fluxes compared with other sources, and also they lack SMA 880 μm observation, we put them into a separate group. G15v2.779 is also included in the table for comparison.
