Spatially resolved spectroscopic maps made using the ellipse fitting method. These use the same signal to noise ratio as the contour binned maps in Fig. 12 but are zoomed to show a larger area and have slightly different colour scales. The ratio map in this case has been smoothed by a Gaussian with σ = 6 arcsec. The ellipses selected have a similar area to the contour binning regions shown in Fig. 12 and have a similar aspect ratio, with many having the maximum 3:1 ratio.
