Line and continuum images. Top panels (from left to right): Continuum image at 249 GHz (in mJy/beam), C18O, and C17O J = 2-1 integrated areas (in mJy/beam.km/s). Bottom panels: SO 56 − 45 (brighter) line, from left to right: Integrated area, peak brightness (in K) and velocity field (in km/s). Synthesized beams are indicated. The white ellipse marks the approximate peak radius of the dust ring.
