Abstract
A methodology for measuring the astronomic climate characteristics of the Baykal astrophysical observatory (BAO) from the analysis of the digital image quality, obtained from a full disk solar telescope is proposed. The image quality is estimated by a modified information-statistical “optimal window” algorithm. A large body of data (several thousand frames) is processed automatically using a hardware-software system, developed at the Zuev Institute of Atmospheric Optics SB RAS on the basis of NVIDIA® CUDA and Intel® IPP & MKL parallel programming technologies. The results of a statistical analysis of solar chromospheric H-alpha filter-grams, obtained on BAO in 2001–2002 by means of a Princeton Instruments 2048B digital camera, are presented.
