Notes.
Full widths half maximum and “observed” CO(2−1) or CO(3−2) line integrated fluxes in Jy km s-1 and their 1σ errors, as derived from fitting Gaussian function(s) to the observed CO profile.
Lensing-corrected CO(1−0) integrated line luminosities obtained with the following prescriptions: (1) the Solomon et al. (1997) formula 
, where νobs is the observed line frequency in GHz and DL is the luminosity distance in Mpc; (2) the correction factors 
and 
adopted for SFGs to account for the CO(2−1) and CO(3−2) transitions being slightly subthermally excited (see Sect. 4); and (3) the lensing magnification correction, μ, given in Table 1.
Molecular gas masses, 
, obtained by assuming the “Galactic” CO–H2 conversion factor XCO = 2 × 1020 cm-2/ (K km s-1), or α = 4.36 M⊙/ (K km s-1 pc2) including the correction factor of 1.36 for helium. The molecular gas fraction is expressed as fgas = Mgas/ (Mgas + M∗). Both quantities correspond to intrinsic values corrected from magnification factors.
4σ upper limit estimated by assuming a full width half maximum FWHMCO = 200 km s-1 for the undetected CO(3−2) line.
“Observed” CO(1−0) integrated line fluxes and their 1σ errors from Riechers et al. (2010).
