The archive of AGN spectral observations is obtained on AZT-8
telescope at the Fesenkov Astrophysical Institute (FAI), Almaty,
Kazakhstan. It represents the result of observations for abot 25 years
- from 1970 to 1995. All observations were carried out at AZT-8 (D =
700 mm, F[main] = 2800 mm, F[Cassegrain] = 11000 mm) with a high-power
spectrograph. In 1967-68, on the basis of the image intensifier
(https://doi.org/10.1080/1055679031000084795a) developed and assembled
the spectrograph of the original design in the workshops of the FAI.
To use the spectra, please, download raw .fit file of required object,
date and exposure. The open 'Calibration frames' in Related links and
then use them to calibrate object spectra frames. For more information

Description:
The First Byurakan Survey (FBS) is the largest and the first systematic
objective prism survey of the extragalactic sky. It covers 17,000 sq.deg.
in the Northern sky together with a high galactic latitudes region in the
Southern sky. The FBS has been carried out by B.E. Markarian, V.A.
Lipovetski and J.A. Stepanian in 1965-1980 with the Byurakan Observatory
102/132/213 cm (40"/52"/84") Schmidt telescope using 1.5 deg. prism. Each
FBS plate contains low-dispersion spectra of some 15,000-20,000 objects;
the whole survey consists of about 20,000,000 objects.
The release consists of event lists and instrument response functions
for observations of various well-known gamma-ray sources (the Crab
nebula, PKS 2155-304, MSH 15-52, RX J1713.7-3946) as well as
observations of empty fields for background modeling.
