Abstract:
Our goals were to analyse 52 photographic and 651 electronic spectra
of beta Lyr to obtain additional information about circumstellar
matter and to investigate spectrophotometric information for the first
time.
Description:
Files table1.dat and table2.dat contain U,B,V photometry of beta Lyr
secured on Hvar Observatory (Croatia) and on Tubitak Observatory
(Turkey). File table3.dat contains radial velocities of both main
radiative components of beta Lyr (donor star and accretion disk).
There values were obtained in spectral disentangling process using
KOREL code (see Hadrava, 2004PAICz..92...15H 2004PAICz..92...15H, KOREL - User's guide).
