Moment-0 and moment-1 maps of the molecular line emission detected towards G09v1.97. Top: CO(6−5). Middle: H₂O. Bottom: H₂O⁺. The contours are shown at −3, −2, 3, 4, 5, 6, 7, 8, 9, 10σ levels for the CO(6−5) and H₂O emission and at −3, −2, 3, 4, 5σ levels for the H₂O⁺ emission. The synthesized beam is shown in the bottom- left of every image, beam sizes can be found in Table 1 for each line. Note: the angular resolution is significantly lower for the H₂O⁺ emission as it was imaged from the combined dataset as described in Sect. 2. A clear velocity gradient is visible in the moment-1 map of the CO(6−5) emission.
