NGC 2369. Top panels show the SINFONI K band continuum emission, the observed maps (not corrected from extinction) of the lines Brγ at 2.166 μm and Brδ at 1.945 μm, together with the AV map. The white contour englobes those spaxels above S/N = 4 considered to build the AV map and distribution. The brightest spaxel of the K band continuum is marked with a plus symbol (+), and has been used as reference to obtain the radial profile in the bottom right panel. The secondary nucleus, if present, is marked with a cross (×). Bottom left panel shows the AV distribution of all valid spaxels (blue histogram) and the distributions of the those spaxels above (red) and below (yellow) the median value of the Brδ S/N distribution. The relationship between the surface brightness of the lines and the AV is shown in the central panel, where the points with AV < 0 are outlined with a black contour. Finally, the radial distribution of the extinction is shown in the bottom right panel, where the blue line represents the mean value of AV for different radial bins and its error. The bins are obtained as the 1/30 of the total radial coverage of the map.

NGC 3256. Same as Fig. 1a but for NGC 3256. Please note that the central spaxel lays outside the FoV since the nucleus was not observed in K-band. See text and Paper I for further details.

IRAS 06206-6315. Top panels show the SINFONI K band continuum emission, the observed maps (not corrected from extinction) of the lines Paα at 1.876 μm and Brγ at 2.166 μm, together with the AV map. The white contour englobes those spaxels above S/N = 4 considered to build the AV map and distribution. The brightest spaxel of the K band continuum is marked with a plus symbol (+), and has been used as reference to obtain the radial profile in the bottom right panel. The secondary nucleus, if present, is marked with a cross (×). Bottom left panel shows the AV distribution of all valid spaxels (blue histogram) and the distributions of the those spaxels above (red) and below (yellow) the median value of the Brγ S/N distribution. The relationship between the surface brightness of the lines and the AV is shown in the central panel, where the points with AV < 0 are outlined with a black contour. Finally, the radial distribution of the extinction is shown in the bottom right panel, where the blue line represents the mean value of AV for different radial bins and its error. The bins are obtained as the 1/30 of the total radial coverage of the map. For those objects with multiple components, the top inset shows the AV radial profile of the system taking the main nucleus as the centre, whereas the bottom subpanel shows the radial profile obtained by extracting the profiles of each component separately and plotting them in the same reference frame.
