Query: Calibration of VERITAS Telescope 1 via Muons   Cherenkov light from cosmic-ray muons is a significant source of background
for the Imaging Atmospheric Cherenkov Technique. However, muon events are also
valuable as a diagnostic tool because they produce distinctive ring images, and
the expected amount of Cherenkov light per unit arclength can be accurately
calculated. We report on a comparison of real and simulated muon events in
VERITAS Telescope 1, using this comparison to validate the detector model and
to determine the light collection efficiency of the telescope.
