We present a survey for Trojan objects conducted on the UH 2.2 m
telescope using a 8192 x 8192 pixel charge-coupled device (CCD) mosaic.
In this survey, 20 of sky were covered to limiting magnitude
V = . Ninety-three Jovian Trojans with size ranging from
about 4 km to 40 km diameter were discovered. The cumulative
magnitude-frequency distribution is found to have slope of . The bias corrected mean inclination is .
The total number of L4 Trojans is estimated at ( ) x
(diameter km). The size and total mass of the L4 Trojan cloud
are discussed. No "Trojans" of Saturn, Uranus or Neptune were discovered.
We will discuss the upper limits to the surface densities of these
