Table 2: Details of NIR observations. "Observing ID'' refers to the number of the data set in column one of Table 1. $\lambda $ is the central wavelength of the broad-band filter used. DIT is the detector integration time in seconds. NDIT is the number of exposures of integration time DIT that were averaged on-line by the instrument. Nis the number of images taken. The total integration time amounts to DIT$~\times~$NDIT$~\times~$N. Seeing is the value measured by the Differential Image Motion Monitor (DIMM) on Paranal at visible wavelengths. It provides a rough estimate of atmospheric conditions during the observations.
