Combination of SINFONI and VISTA K-band images used in the computation of the stellar potential. Top: map of the adopted K-band image, combining the SINFONI map in the central 8″ and the VISTA-K image at a large scale. From the total image at left, we subtracted a small spherical bulge in the right image. Bottom: corresponding de-projected images, where the major axis is now horizontal. The axes are shown in″ and the color bar is the same for the four images.
