ADC_Keywords: Blue objects ; Galaxies, UV-excess 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 < δ < 45 deg and δ > 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. File Summary:

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)
