1st moment (velocity, left two panels) and 2nd moment (velocity dispersion, right two panels) color maps of the CO(6–5) and H2O(211−202) line emission overlaid by the 0th moment (velocity-integrated line emission) contours. The images reveal the strongly lensed kinematic structure of G09v1.97 in the image plane in both CO(6–5) and H2O(211−202), with a significant velocity gradient seen in the northeastern and southern components. The CO and H2O lines trace similar kinematic structure as shown by the close correspondence between their first and second moment maps.
