Nota Bene: the zero points after the Nov 2005 intervention (and mirror aluminization): 23.23+/-0.04, 23.02+/-0.03, and 22.41+/-0.01 for J, H and Ks Large Field Mode, respectively. This result is based on 15, 16 and 14 measurements respectively, over 7 nights in the period from Nov 20 to Dec 13, 2005. Atmospheric extinction coefficients were also determined.
