Fig. 8


Moment 1 velocity field of HCN J = 1 → 0, clipped at the 5σ level. Contours are 440, 520, 600, and 680 km s−1 from lower right to upper left. Primary beam correction and Briggs weighting (robustness parameter +2.0) have been applied. Therestored beam (2.′′52 × 2.′′ 17, PA = 78°) is shown in the lower left corner of the image. The cross indicates the λ ≈ 3 mm radio continuum peak.
