Notes. The redshift is indicated by z, DL is the luminosity distance (PL12), Fbroad the flux of the broad component (see Sect. 3.1), Δv = vpeak(broad) – vpeak(narrow) the velocity difference between peak of the broad and the peak of the narrow component, FWHM the full width at half the maximum intensity of the components in the line-profile, vmax(broad) = Δv – (FWHM/2) the maximum outflow velocity (e.g., Rupke et al. 2005; Arribas et al. 2014), Rbroad the total extent of the broad component, M(hot H2) the derived mass of the hot molecular gas (Sect. 3.1.2), and Ṁ(total H2) the estimated mass outflow rate of the total (hot + cold) molecular gas, assuming a hot-to-cold gas mass ratio of 6 × 10-5 (Sect. 3.1.2). The measurements of Fbroad and Rbroad are derived from the flux and velocity maps of Figs. 2−5, while Δv, FWHM, and vmax(broad) are derived from the H2 line profiles shown in Fig. 6. For additional properties of the narrow-component emission, we refer to PL12 and Appendix A.
Based on a hot-to-cold molecular gas mass ratio of 6 × 10-5 (Emonts et al. 2014; Pereira-Santaella et al. 2016).
