Integrated spectra of the five QSO2s with CO(2−1) detection. J1010, J1100 and J1509 show double-peaked CO profiles characteristic of rotating disks. J1356 and J1430 show very broad CO profiles, indicating the presence of different emission-line components. For J1356 we also include the spectrum of the N nucleus only (J1356N). In all panels, v = 0 km s−1 corresponds to the CO frequencies listed in Table 5.
