Map of spectra recorded in individual spaxels. The total area corresponds to the dashed rectangle in Fig. 8; it covers 14 × 16 spaxels (2.8′′×3.2′′). North is up and east to the left. The blue lines show the measured spectra, and the red curves the Gaussian fits. The spectral range is 4955–4980 Å. The black number inside each subplot (top left corner) is the peculiar velocity in km s-1 computed from the Gaussian fit; the red number just below is the FWHM of the emission line in km s-1; the purple number (top right) is the amplitude of the Gaussian in units of 10-20 erg s-1 cm-2 Å-1 spaxel-1. The dashed vertical line marks the average emission wavelength (4970.0 Å). The quasar lies in the upper left quadrant, in the spaxel [7, 5] just next to spaxel [7, 4] (where [1, 1] and [7, 8] define the lower left and upper right spaxels).
