Fig. 8


Data, model, and residual integrated intensity maps. H2CO 303–202 data and model maps are created after applying a Keplerian mask to the image cube (see Sect. 3.1). Left: H2CO 303–202 data integrated intensity map from 0.76–10.84 km s-1 and C18O 2–1 data integrated intensity map from –0.88–12.48 km s-1. Synthesized beam and AU scale are shown in the lower corners. Center: integrated intensity map of best-fit model taken over the same velocity channels as the left figure. Right: residual image with contours at 3σ intervals. Dashed contours are negative, solid contours are positive.
