Notes. Regions A-E correspond to the CO(1-0) source regions, while the regions 1–3 correspond to the cold dust regions, as defined by Fogarty et al. (2019). We have extracted from the MUSE cube integrated spectra corresponding to these 8 regions, and we have computed the systemic velocity and velocity dispersion of the Hα gas, the electron density ne, the electron temperature Te, the colour excess E(B − V), the ionisation parameter log(U), the SFR [M⊙ yr−1], and the oxygen abundance 12 + log(O/H). The las row of the table refers to the integrated spectrum of the whole (90 × 90 spaxels) sub-cube, displayed in Fig. C.1.
