The [O III] 5007 flux as a function of distance from the nucleus. The blue points show the spaxels in the nuclear region, orange points show the NE nebula, and red points show the SW nebula. The black dashed line shows a fiducial r⁻² trend. The horizontal black dotted line shows the median flux in the NE nebula. The [O III] flux of the NE nebula deviates from the inverse square trend and displays a relatively flat trend in distance. This is not consistent with a simple AGN photoionization model originating from the nucleus, but it may result from in situ shock excitation.
