Table 2: A summary of the observations taken with ISAAC. The exposure times and detection limits of the mosaic refer to the central part of the mosaic, where the exposures are deepest. In other areas, the exposure time will vary from one quarter to one half of this depending on the overlap. The detection limit is defined as the $5 \sigma$ detection threshold over an 0 $.\!\!^{\prime\prime}$ 9 diameter aperture.
