### Description

Gamma ray earthbound & satellite experiments have observed over the last years many Galactic and extragalactic gamma ray sources. The detection of astrophysical neutrinos emitted by the same sources would imply that these astrophysical objects are charged cosmic ray accelerators and help to resolve the enigma of the origin of cosmic rays. A very large volume neutrino telescope will be able to detect these potential neutrino emitters. The apriori known direction of the neutrino source can be used effectively to suppress the $^{40}K$ optical background through causality filters. We report on advanced filtering and prefit techniques using the known neutrino source direction and first results are presented.
