The CLUE experiment studies primary cosmic rays (E > 2 TeV) by detecting UV
(190-230 nm) Cherenkov light produced by atmospheric showers. Since atmosp
heric absorption in the UV range is higher than in the visible range, CLUE
cannot apply algorithms normally used in IACT(1) experiments to determine p
rimary cosmic-ray direction. Tn this paper, we present a new method develop
ed by CLUE. The algorithm performances were evaluated using simulated showe
rs. Preliminary results of the source analysis using this new method are sh
