Selected channel maps showing the ¹²CO channels in color and the 3σ outline in purple, the HCO⁺ emission 3σ outline with black contours, and the continuum contours in white. In the top right corner of each panel we note the v_lsr in white with the velocity with respect to the systemic velocity of 4.75 km s^-1 in parenthesis. The clean beam is shown in orange in the bottom left corner of each panel. Note the foreground absorption for the CO emission in the leftmost panels, and the emission inside the disk gap in the rightmost panels. Complete channel maps are shown in Fig. A.1.
