A Catalogue of galaxies with UV-Continuum (Markarian galaxies) detected during
the First Byurakan Survey (FBS) is presented. The purpose of the Survey was
to search for peculiar faint extragalactic objects with UV-excess radiation
and to study them. The procedure of the observations and processing, the Survey
areas, the object selections and classification creteria and also several
selection effects are described. The Catalogue contains the following initial
data on all the objects: the precise coordinates, visual magnitudes, angular
sizes, redshifts and classification types.
The observational results of slit spectra, UBV-photometry, IR-photometry
(IRAS-data), morphology and some other data are also included into the Catalogue.
While compiling the Catalogue the authors introduced some necessary corrections
in the earlier published lists on galaxies with UV-continuum. In addition we
included the objects with numbers 1501-1515. In most cases they are well-known
Seyfert galaxies omitted by the authors in the lists, but detected on the
plates. 41 objects from our lists are not included into the Catalogue, since
they are either stars of our Galaxy or star projections on the galaxies.
The Catalogue presents the largest homogeneous sample of AGN of different types
on the northern sky for bright objects ( <16.0m).
Up to the middle of 1987 the redshifts were measured for 1459 from 1969 objects
of Catalogue.
The catalogue description
Below we describe in detail the parameters of FBS objects Catalogue presented
in Table 7.
1. - Name of galaxies
2,3 Coordinates (1950). Since all Markarian galaxies were observed with
radio telescopes, their precise coodinates were measured by some authors.
We present them in the Catalogue:
