keyword=Rich angle resolutionThe figure shows the Cherenkov angle reconstruction with the
RICH for aerogel selected pions (top) kaons (central) and
protons (bottom). A selection on the central momentum +/- 1% has been
applied since the Cherenkov angle DOES depends on the momentum, the
dependence being larger for kaons and protons than for pions.
Resolutions of 4.5, 5.5 and 6.2 mrad have been obtained for pi,K,P, respectively.
