Dome C site testing: long term statistics of integrated optical turbulence parameters at ground level
Abstract We present long term site testing statistics based on DIMM and GSM data obtained at Dome C, Antarctica. These data have been collected on the bright star Canopus since the end of 2003. We give values of the integrated turbulence parameters in the visible (wavelength 500 nm). The median valu...
