Notes.

(a)

Deconvolved radius (0.5 × FWHM) of the nuclear CO(2–1) Gaussian emission model.

(b)

Nuclear CO(2–1) flux derived from the Gaussian model. This value does not include extended CO(2–1) emission beyond r > 0.7 kpc. In addition to the statistical uncertainties listed in this column, the absolute flux accuracy is ∼10%.

(c)

Molecular gas mass calculated using a ULIRG-like αCO conversion factor (0.78 M (K km s−1 pc−2)−1) and a CO 2–1 to 1–0 ratio r21 = 0.91 (see Sect. 4.3).

(d)

CO(2–1) surface density within rCO calculated as .

(†)At the resolution of these observations (370 pc) it is not possible to disentangle the CO(2–1) emission from the two nuclei of F15327+2340 (see Fig. B.1).
