Table information for 'spectra_agn_archive.data'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: 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.
