Moment maps and radial profile of H2CO 303–202. Left: moment 1 map from 0.76–10.84 km s-1, clipped at 3σ. Solid black contours show the 225 GHz/1.3 mm emission at 5.0 × 10-5 (1σ) × [5, 10, 25, 50, 100, 300, 500, 1000, 1500, 2000] Jy beam-1. Synthesized beam and AU scale are shown in the lower corners. Center: moment 0 map integrated over 0.76–10.84 km s-1 after applying a Keplerian mask. Synthesized beam and AU scale are shown in the lower corners. Right: radial intensity curve from azimuthally-averaged elliptical annuli projected to i = 44°, PA = 133°. Shaded gray area represents 1σ errors.
