Integrated intensity map of the CN emission overlaid with eight enumerated circles representing the eight single-beamwidth (0.3′′ radius) regions from which we extract spectra at each side of the disk at radii > 210 au (see Table 4, Sect. 3.3, and Fig. 7). The synthesizedbeam size is indicated by the white ellipse. Vertical dashed green lines are placed at radii of ~210 au from the central star; the horizontal dashed green line indicates the disk midplane.
