Notes. The reported outflow velocities, v_out, correspond to the projected velocities. The uncertainty in α_CO = 0.8 ± 0.5 M_⊙(K km s⁻¹ pc²)⁻¹ (Downes & Solomon 1998) is included in the mass error estimates. For J1347, the values reported for scenario I^a are the nuclear outflow properties derived from CO(1–0) data at 0$\stackrel{″}{.}$05 resolution by Holden et al. (2024) and for scenario III^b, the upper limits reported by Lamperti et al. (2022) for the unresolved outflow detected in CO(2–1), using the average outflow velocity and radius of 390 km s⁻¹ and 0.52 kpc that they adopted for nondetections. For J1356, the values reported for scenario I^c correspond to the CO(3–2) outflow measurements reported by Sun et al. (2014), but adopting an outflow velocity of 400 km s⁻¹ instead of the maximum outflow velocity used by these authors (500 km s⁻¹), and scenario III^d to the measurements from RA22, which correspond to outflowing gas along the kinematic minor axis. The outflow mass fractions were computed using the total masses of M_H2 listed in Table 3, except for J1356, for which we used the mass of J1356N reported by RA22, of M_H2 = 6.39 × 10⁹ M_⊙. For J1509, M_H2 = 17.6 ± 7.4 M_⊙ (RA22).
