Notes. For each target we report the observed CO(2−1) frequency, the rms representative of the spectral region next to CO (for a channel width of 10 km s−1), integrated CO flux, FWHM of the line profile, CO luminosity and maximum spatial extent of the CO emission at 3σ measured from the AGN position. ( * )Upper limits at 3σ assuming FWHM = 430 km s−1 and a circular aperture of RCO = 2.9 kpc (mean values of the three ETGs with CO detection). ( † )The asymmetric CO emission line profile of J1356 can be better fitted with two components of FWHM = 184 ± 25 and 550 ± 65 km s−1. The last three columns list the gas masses estimated by assuming R21 = 1 and αCO = 4.35 ± 1.30 M⊙(K km s−1 pc2) −1, corresponding depletion timescales (tdep = MH2/SFR) and H2 gas fractions (fH2 = MH2/M*).
