Examples of individual, fully reduced, and sky-subtracted data cubes of HD 106906 b in J, H, and K band, median-collapsed in spectral direction. The bright region in the bottom right is created by the primary star just outside the field of view. Dark patches are visible where the sky image contains stars. An example aperture for the extraction of the spectra (r = 0.̋26) is superimposed on HD 106906 b on the K-band image in red. Panels show the full field of view of SINFONI (8 × 8′′); centering is subject to jitter offset. The color stretch is linear, the orientation of all panels as indicated in the K_s image.
