Description:
I, J, K magnitudes of 767 asteroids (numbered between 1 and 8000)
are presented here. These asteroids have been recovered in the DENIS
Survey (Deep European Near-Infrared southern sky Survey) on the basis
of their predicted ephemerides. The observations were performed with
the 1m-telescope at ESO, La Silla (Chile). The limiting magnitudes of
the three bands I, J, K centered at 0.8, 1.25 and 2.15 microns are
respectively 18.5, 16.5 and 13.5.
