III/245      Catalogue of H line profiles of 235 B-F stars    (Klochkova+, 2006)

Catalogue of hydrogen line profiles of 235 B, A, F-stars' spectra. Klochkova V.G., Nasonov D.S. <Special Astrophysical Observatory, Russia (2006)>
ADC_Keywords: Stars, A-type ; Stars, B-type ; Stars, F-type ; Equivalent widths Description: There are given 1064 profiles of the hydrogen lines Hγ and Hδ for 235 B,A,F-stars obtained at the Main Stellar Spectrograph of the 6-m telescope in 1978-1986 in the course of several large observing projects. Optical density close to D=1.0 was reached for all spectra on Kodak IIaO photographic plates. The profiles are presented as smoothed intensity normalized to the level of local continuum for different distances from lines core, in Å. The blue and red wings of Hγ and Hδ lines are averaged.
