DCO+ J = 3 − 2 channel maps from 5.74–7.95 km s−1, Hanning smoothed to 0.17 km s−1 channels. Black contours show 5.5 mJy beam−1 (1σ) × [3, 6, 9]. The blue contours show the outline of the Keplerian mask. Channel velocity is shown in the upper-right corner. The synthesized beam and AU scale are shown in the lower-left panel.
