Moment maps of the detected CO isotopologs. The left column shows ¹²CO (2–1) , the middle column shows ¹³CO (2–1) , and the right column shows C¹⁸O (2–1). The top row shows the peak intensity map, the center row shows the intensity-weighted velocity map, and the bottom row shows the integrated intensity map. The synthesized beam is represented as a filled ellipse at the bottom left side of every panel. The green contours represent the disk continuum emission with 10, 150, and 200 times the rms. The white contours represent 3, 5, 7, 9, 11, 13, and 15 times the rms (1σ = 9.5 mJy beam^-1 km s^–1) for the ¹²CO (2–1) moment 0 map; 5, 7, 9, 11, 13, and 15 times the rms (1σ = 2.7 mJy beam^-1) for ¹²CO (2–1) moment 8; 3, 5, 7, 9, and 11 times the rms for ¹³CO (2–1) moment 0 (1σ = 4.0 mJy beam^–1 km s^–1) and 8 (1σ = 4.2 mJy beam^–1); and 3, 5, 7, 9, 11, 13, 15, and 17 times the rms for C¹⁸O (2–1) moment 0 (1σ = 3.5 mJy beam^–1 km s^–1) and 8 (1σ = 1.8 mJy beam^–1).
