Absolute monochromatic fluxes in the ultraviolet spectra of stars according to the data of orion-2

A method for making the transition from the relative scale of measurement of the ultraviolet spectrograms of stars photographed by means of Orion-2 to the scale of absolute energy units (erg per sq cm per sec per A) is presented. The method is then applied to a group of 30 stars in the region of Aur...

Zusammenfassung:A method for making the transition from the relative scale of measurement of the ultraviolet spectrograms of stars photographed by means of Orion-2 to the scale of absolute energy units (erg per sq cm per sec per A) is presented. The method is then applied to a group of 30 stars in the region of Auriga, around Capella (Alpha Aur). The results are given in both tabular and graphical form. The spectral classes of the stars are in the range B2-K2, and the photovisual magnitudes range from 5.6m to 9.5m.
