Its main characteristics are the low energy threshold (100 GeV) and substantial flux sensitivity (1% Crab units). The combination of the four telescope data analysis provide good background rejection and angular resolution. Recent results on the performance and operation are reported here. %G English %Z HESS %L in2p3-00025063 %U https://hal.in2p3.fr/in2p3-00025063 %~ IN2P3 %~ LPTA %~ CNRS %~ UNIV-MONTP2 %~ UNIV-MONTPELLIER %~ UM1-UM2
