Role of Group and Phase Velocity in High-Energy Neutrino Observatories
Kuzmichev recently showed that use of phase velocity rather than group
velocity for Cherenkov light signals and pulses from calibration lasers in
high-energy neutrino telescopes leads to errors in track reconstruction and
distance measurement. We amplify on his remarks and show that errors for four
cases of interest to AMANDA, IceCube, and RICE (radio Cherenkov detector) are
negligibly small.Comment: To be published in Astroparticle Physics, 6 pages, uses elsart.st
