Notes.

^(a)

Redshifts are taken from D10.

^(b)

Velocity range for the flux measurements.

^(c)

Average of the three BzK galaxies with all four transition measurements (BzK-4171, 16000 and 21000). Uncertainties are standard errors of the mean.

^(d)

Continuum flux density at the rest frequency of CO[5–4] (the CO fluxes listed in this table were all corrected for the underlying continuum).
