Channel maps of the [C I] (2−1) cube, showing every other channel. The grayscale and the blue contours show the observed [C I] (2−1) data. The red contours show the best-fit rotating-disk model (Section 4). The contour levels are at S/N = ( ± 2, 3, 5), and negative contours are shown with dashed gray lines. The axis coordinates are relative to the kinematic center (golden star). The line-of-sight velocities are relative to the redshift of the [C I] (2−1) line. The synthesized beam of the [C I] (2−1) cube is shown in the bottom left corner of each panel.
