Kinematic deviations in the AS 209 disk using the CO data from MAPS (Öberg et al. 2021). The deviations show variations < 1% at the location of the CO column-density gap, which is illustrated by the vertical dotted line. The continuous profile is the expected profile through a convolution with a 0.″15 resolution (∼18 au). The recovered deviations seem consistent with the profile obtained by Teague et al. (2018) with lower-resolution data, reassuring us that the kinematic deviation in AS 209 is not strong enough to cause a deep gas gap at 59 au.
