Velocity-based estimate of the kinematic position angle of NGC 1427A. The panels show the stellar velocity field (top left), stellar surface-density map (top right), Hα velocity field (bottom left), and H I velocity field (bottom right), all displayed over the same sky region. The cyan ellipse marks the common aperture adopted for the fit. The green line indicates the fitted kinematic major axis, and the white dashed line shows the axis of rotation.
