Notes. All CO parameters refer to the J=(4–3) transition;

(a)

L(IR) is the 8–1000μm luminosity in L, Mstellar the stellar mass, and SFR the star-formation rate (see Sect. 2 and Polletta et al. 2008a);

(b)

ν is the observed frequency of the CO line fitted with a single Gaussian. ν1 and ν2 are the observed frequencies of the two CO peaks obtained with a double Gaussian fit, and FWHM, FWHM1, and FWHM2 are the corresponding full-widths-at-half maximum;

(c)

velocity offset between the peaks of the double Gaussian fit;

(d)

intensity derived from each component of the double Gaussian fit;

(e)

LCO is the CO line luminosity, in L;

(f)

is the integrated CO luminosity, in K km s-1 pc2;

(g)

Mgas is the gas (H2+He) mass;

(h)

SFE is the star-formation efficiency defined as L(FIR)/ (see Sect. 5.3).
