PNLF of FCC 153 for in-plane and off-plane regions. Top panel: map of the [O III] λ5007 line. The blue circles represent the detected PNe in central pointing whereas the green ones show the detected objects in the halo pointing. The black dashed lines indicate the separation between in-plane and off-plane regions. Bottom panels: PNLF of both components: in-plane (left panel) and off-plane (right panel). The blue histograms as well as the blue solid and dashed lines represent the PNLF for PNe in the central pointing, whereas the green histograms along with the green solid and dashed lines indicate the PNLF for the PNe in the halo pointing. The red contours are the isophotes of the flux white image.
