Moment 1 map of the CH3CN J = 13–12 emission (K = 3 projection). The color scale unit is km s−1. The black contours represent the continuum emission at 334 GHz. Levels are at 15, 30, 50, 80, 140, and 200 mJy beam−1. The beam is indicated in the top right corner. The solid and dashed lines show the approximated directions of the disk and its rotation axis, respectively.
