| dc.description | First results concerning the performance characteristics of the HEGRA IACT array are given, based on stereoscopic observations of the Crab Nebula with four telescopes. The system provides a gamma-ray energy threshold around 0.5 TeV. The Crab signal demonstrates an angular resolution of about 0.1 deg. Shape cuts allow to suppress cosmic ray background by almost a factor 100, while maintaining 40% efficiency for gamma-rays. The Crab signal is essentially background free. For longer observation times of order 100 h, the system in its present form provides sensitivity to point sources at a level of 3% of the Crab flux. Performance is expected to improve further with the inclusion of the fifth telescope and the implementation of advanced algorithms for shower reconstruction. | |
