Channel maps of the ¹²CO J = 2–1 line emission toward the Flying Saucer. Contours are in steps of 15 mJy/beam (1.22 K, approximately 7σ): negative contours are in red, positive contours in black, zero level contour omitted, and the color scale is given on the right. The cross indicates the position and orientation of the dust disk. The LSR velocity (in km s^-1) is indicated in the upper left corner of each panel.
