Top: position-velocity diagram along the kinematic major axis (PA ). The magenta line indicates the best-fit circular rotation curve obtained with DISKFIT. Bottom: position-velocity diagram along the kinematic minor axis (PA ). The magenta horizontal line indicates the best-fit systemic velocity of the galaxy (3568 ± 7 km s⁻¹). The solid red and dashed purple contours delineate the section of the 3D mask we used to integrate the outflow region and its symmetric region across the kinematic minor axis, respectively.
