Fig. A.3


Signal-to-noise ratio (S/N) achieved for the brightest pixel vs. the background noise in the combined cube (black). For comparison the expected and almost identical S/N is shown, simulated using the exposure time calculator (ETC) of ESO/SINFONI (blue). In red we present the final achieved S/N of the extracted companion spectrum after removing a superimposed spike (Fig. 3), as shown in Fig. 4.
