Median in wavelength direction of the reduced VLT/SINFONI integral field cubes. Left: cube after reduction. Centre: cube after removing the primary halo, assumed to be centred at the separation of 1.85′′, as measured in the VLT/NACO images. North is about 70° from the right-hand side towards the bottom of the plots. Right: cube after removing the primary halo, spectral deconvolution, and polynomial flattening of the resulting background, used for the extraction of the final spectrum.
