Notes. zCO is derived from the error-weighted mean of the multi-J CO spectral redshifts from this work. For the double-peak sources, we take an average redshift of the two components. The luminosity distance DL is calculated using Cosmology.jl with the Julia language (Bezanson et al. 2012) and the errors are propagated using Measurements.jl (Giordano 2016). We also recall values of LIR in this table. For 
, most of the values are converted from CO(3–2) fluxes as described in the text. For G09v1.40, we use CO(2–1) /CO(1–0) ratio to infer the flux of CO(1–0) . And for NAv1.56 and G15v2.779, we use CO(4–3) /CO(1–0) ratio (flux ratios are from Bo13). The calculation of apparent molecular gas mass μMH2 takes a conversion factor αCO = 0.8 (see text). μMH2,Ha is the molecular gas mass calculated from CO(1–0) fluxes reported in Harris et al. (2012). Gas mass Mgas is calculated by considering a 36% helium contribution, e.g. Mgas = 1.36MH2. δGDR and tdep are gas to dust mass ratio and molecular gas depletion time, respectively (see the detail definitions in Sects. 4 and 5.3). (a) Because of the limited data quantity, we take the NOEMA CO(4–3) data of NAv1.56, which offers better accuracy (Oteo et al., in prep.). (b) The physical properties of G15v2.779 are taken from or computed according to Cox et al. (2011) and O13.
