Fig. 5.

Detection limit map derived from our NACO Lp-band observations. Detection limits are given in relative contrast to the primary star. We indicate the expected position of the companion with a black, dashed circle. The companion was not detected in these observations and should thus exhibit a contrast larger than 8.2 mag relative to CS Cha.
