Method of estimating time scales of the atmospheric piston and its application at Dome C (Antarctica)
International audience Analysis of the first interferometric fringes recorded at Dome C, Antarctica are presented. Measurements were taken 31 January and 1 February 2005 during daytime. Our purpose in performing the analysis was to measure temporal fluctuations of the atmospheric piston, which are c...
