Maps for the A/rN ratio between the [O III] 5007 Å line amplitude and residual-noise level derived from our spaxel-by-spaxel spectral fit to the MUSE spectra. Both central and halo pointing are shown, with detected [O III] sources identified by coloured circles: Blue for central PNe, red for Disk (or Middle) PNe and green for Halo PNe. Isophotes are spaced at one mag arcsec⁻¹ intervals. The grey dashed regions indicates the area excluded from our PNe analysis.
