Velocity field maps (shown in colors) in each of the molecular emission and absorption lines detected in HerBS-89a superimposed on the continuum at the individual frequencies of each molecular line (in contours of 10σ spacing). The velocity maps were obtained above 3σ thresholds in the zero-th moment map of the molecular lines. As in Fig. 4, the three top rows display the high-angular resolution data, whereas the lower row shows the lower-angular resolution images. Upper right panel: combined ¹²CO(9 − 8) and H₂O(2₀₂ − 1₁₁) image that reveals the kinematics along the western arm of the partial Einstein ring. Right panel in the second row: combined velocity field of the two OH+ absorption lines ((1₁ − 0₁) and (1₂ − 0₁)). The synthesized beam is shown in the lower left corner of each of the images.
