Overview of the emission line analysis. Top panels: BPT diagrams showing the flux ratios of [OIII]/H_β in comparison with [NII]_6584Å/Hα (left), [SII]_6717+6731Å/Hα (middle), and [OI]_6300Å/Hα (right). Only spaxels where the relevant lines have S/N > 5 are shown. The solid grey lines show the demarkation line between AGN and star formation regions from Kewley et al. (2006), the grey dashed line shows the demarkation lines from Kauffmann et al. (2003). Bottom panels: Extinction map (left) showing the V-band extinction assuming the extinction law from Calzetti et al. (2000). Right: surface density of the SFR obtained by converting the Hα flux. The greyscale image in the background shows the flux of the MUSE white-light image for visualisation.
