Top panel: Phoenix feature as observed in the B6SB 259 GHz continuum compared to the B7 CO(3-2) molecular tracer (blue contour at 1.0 mJy/beam km/s). We observe a mismatch between the continuum and CO(3-2) morphology, which either implies that the Phoenix feature is associated with a polar outflow perpendicular to the CND or that the inner spiral arm structure traced by dust differs from the molecular spirals. Bottom panel: Illustration of both of these scenarios. The spiral pattern drawn in purple is based on the structure observed in the right panel of Fig. 5. The B6SB 259 GHz continuum contours are drawn at [6, 8]  ×  rms, with rms = 0.022 mJy/beam.
