Displaced nucleus of NGC 1023. Top panel: offset radius profile with respect to the photometric center of the galaxy. Bottom panel: selected outer isophotes (in black) with their respective fitted ellipses (blue) are overplotted on r-band image. The blue pluses are their respective centers, while the red point is the photometric center of the galaxy, and the green point is the photometric center of GCs candidates. The top-right inset is a zoom-in of the inner part to better see the displacements. The blue points in the offset radius profile are the offsets for the selected isophotes.
