Abstract (from CDS):
Principal attention is given to measurement of the optical-turbulence altitude distribution, which is the most important characteristic affecting the performance of optical telescopes. For the period from 2007 November-2009 October, more than 85000 turbulence profiles were collected using the combined Multi Aperture Scintillation Sensor and Differential Image Motion Monitor (MASS/DIMM) instrument. The statistical properties of the turbulent atmosphere above the summit are derived and the median values for seeing β0= 0.93arcsec and free-atmosphere seeing βfree= 0.51arcsec are determined. Together with the estimations of isoplanatic angle θ0= 2.07arcsec and time constant τ0= 2.58 ms, these are the first representative results obtained for Russian sites, and are necessary for the development of modern astronomical observation techniques like adaptive optics.
