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.
