4C +01.30: An X-shaped jetted structure with the active jet traced by the yellow–red regions and a nearly orthogonal secondary feature (wings) traced by the green–cyan regions (1.4 GHz VLA FIRST survey map; Wang et al. 2003). The inset displays the host galaxy in optical bands (DECaLS DR10 grz composite), with ellipsoidal isophotal contours overlaid to illustrate its geometric axes: the active jet follows the major axis, wings follow the minor axis.
