Moment 1 maps of the CH₃OH 20(−2,19)–19(−3,17)E and CH₃OCHO 20(1,19)–19(1,18) transitions. The color scale unit is km s⁻¹. Black contours represent the continuum emission at 334 GHz. Levels are at 15, 30, 50, 80, 140, and 200 mJy beam⁻¹. The beam isindicated in the top right corner of each panel. The solid and dashed lines show the approximated directions of the disk and its rotation axis, respectively.
