Scientific paper

The absolute energy distribution in the Vega spectrum was determined on the basis of measurements performed during 1982-1987 in the mountains of Tien Shan at a height of 2800 m. Observations were made with a 20-cm Cassegrain telescope and covered the 3200-7500-A range; the standard sources of radiation were five tungsten ribbon-filament lamps, which were calibrated at institutes in Leningrad and Moscow, and at the NBS. The spectral energy distribution for Vega is presented, and the results are compared with those obtained previously.
