Site Testing At Dome C: History, Present Status & Futur
International audience Here we present why we decided to undertake a site characterization at Dome C, Antarctica following a first step made at South Pole. It was clear that poor seeing measured at South Pole was mainly due to ground catabatic wind interacting with strong vertical temperature (refra...
