| Sumario: | Čerenkov ring images from single muons have been used to calibrate the Whipple Observatory 10 m imaging telescope. This approach tests the total throughput of the telescope and uses a known atmospheric Cerenkov light signal that closely matches the spectrum of the atmospheric Čerenkov signal from an air-shower. The absolute calibration is derived by matching the observed ring images with those predicted by a simple geometrical and physical model; a value of 1.25 ± 0.13 photoelectrons equivalent to 1 digital count was found. Using this value simulations indicate that the telescope had an energy threshold of 300 GeV when this calibration was made. |
