ALMA CO(2-1) spectrum of one of the CO ‘blobs’ along feature C in Fig. 11 (one ALMA spaxel centred on RA = 204.266, Dec = −29.8665). The spectrum has been corrected for the systemic velocity. We observe three separate Gaussian velocity components. The component at v_CO ∼ −30 km s⁻¹ is associated with the spiral arm in the galaxy, and the component at −20 km s⁻¹ traces broadening around the first one, likely associated with a bar orbit. We interpret the third component at v_LSR ∼ 80 km s⁻¹ as being associated with infalling material.
