Description:
The First Byurakan Survey (FBS), also known as the Markarian survey,
covers about 17000 sq. deg. It has been used by Markarian and his
collaborators to search for UV excess galaxies (see Cat. VII/172)
and by Abrahamian and his collaborators to search for UV excess or
emission line starlike objets. The identification, classification, and
investigation of all blue stellar objects in the Survey constitutes
the second part of the First Byurakan Survey and is a natural
continuation of it.
For this second program, at the present time, 4109 sq. deg. have been
searched (33 < {delta} < 45 deg and {delta} > 61 deg, excluding the
galactic plane) and a catalogue of 1103 blue stellar objects has been
built. It has been published in a series of eleven papers referenced
in the "References" section below.
More details can be found in Mickaelian et al. 1999, Astrofizika 42,5:
'On the nature of the FBS blue stellar objects and the completeness of
the Bright Quasar Survey'.
Some accurate optical positions were measured by M. Veron, replacing
the original FBS position.

Note on Type: this Type is made of two parameters:
1. The first parameter (related to B-V index) describes the ratio of
the intensities of the red and blue regions of the spectrum:
'B' means that the blue part is stronger than the red part
'N' means that the intensities of the two parts are equal
2. The second parameter (related to U-B index) characterizes the
intensity of the ultraviolet region of the spectrum:
'1' means that the blue-violet part is approximately 1.5 times
longer than the red-yellow part
'3' means that the blue-violet part is approximately as long as
the red-yellow part
'2' describes the intermediate situation.
In addition, the existence of emission details is noted by 'e' or 'e:',
and absorption details by 'a' or 'a:'
Note on survey: the other surveys are
PG = Palomar Green survey (see Cat. II/207)
CBS = Case Blue Stars (Pesch and Sanduleak, 1983-95)
CSO = Case Stellar Objects (Pesch and Sanduleak, 1983-95)
KUV = Kiso UV excess objects (Nogushi et al., 1980AnTok..18...55N 1980AnTok..18...55N)
