Notes. Integrated flux, velocity, and FWHM obtained through Gaussian fits. Velocities are counted from the central redshifts indicated in Table 1 for the companion galaxy. The H2 masses are estimated within the CO(1–0) beam of 23″, with the standard conversion factor of the Milky Way α = 4.36 M⊙ (K km s−1 pc2)−1. Upper limits are given at 3σ, assuming an FWHM of 300 km s−1.
