Upper panel: HST continuum subtracted [OIII] image of the galaxy showing the location of the slits and the extraction apertures. The images have been convolved with a Gaussian of FWHM = 1′′ to simulate the seeing conditions during the spectroscopic observations. Middle and lower panels: these two figures are a zoom into the nuclear region of the galaxy. The figures show in detail the main regions of interest that are later analyzed in the paper (see the text for details) and the apertures that cover those regions. (A color version of this figure is available in the online journal).
