Analysis of stellar ultraviolet fluxes obtained by "Orion-2"

A comparative analysis of the stellar fluxes obtained by the space telescope "Orion-2" in the wavelength region 2000-3800 A with that of obtained by the IUE, OAO-2, ANS, S2/68, as well as with the ground-based observations are carried out. The agreement between the "Orion-2" data and those of the mentioned experiments is within 10-15% for the 80% of the considered stars. An increase of deviations of "Orion-2" fluxes at 3500 A is noticed for a small number of stars around α Aur. A linear dependence of the "Orion-2" ultraviolet flux deviations from the wavelength is noticed for a group of, in two regions of sky α Aur and ɛ Ori. The corrected data for the long-wavelength path (3500-3800 A) of the reduction curve of the "Orion-2" telescope is presented.
