Position-velocity diagrams of HZ4 extracted along the major (left panel, PA = 200°) and minor (right panel) kinematic axis using a pseudo-slit of 0.4″ width. The black contours in the left panel show 3, 5, 8, and 10σ contours (1σ = 0.1 mJy beam−1), and in the right panel they represent 2, 4, 6, and 8σ contours. The white contours show the best-fit DYSMAL model at corresponding similar contour levels.
