Example of a multi-spin galaxy: PGC 046832. This galaxy has five visible changes of the rotational orientation. Left: Kinematic position angle as a function of radius (1 kpc ∼ 1″). The photometric major axis is shown with a dashed black line, and the median position angles of five components are highlighted with short orange lines. Middle: Observed velocity map. Right: Reconstructed velocity map using low-order KINEMETRY coefficients highlighting only the rotational component of the velocity map. The solid and dashed red lines are the project major and minor axes of the galaxy, respectively. Along the major axis in projection, there are three reversals of the short-axis rotation (prograde, retrograde, prograde), while along the minor axis in projection, there are two (prograde and retrograde), making this galaxy a case with five multi-spin components.
