First Byurakan Survey (FBS) Late Type Stars catalog. Abrahamyan H.V. <Byurakan Observatory, Armenia (2007)>
ADC_Keywords: Stars, late-type ; Spectral types ; Stars, variable ; Infrared sources ; Photometry Keywords: catalogs - surveys - stars: carbon - infrared: stars 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), by Abrahamyan and his collaborators to search for late type stars and UV excess or emission line point sources (stars and starlike objects). The identification, classification, and investigation of late type stars and blue stellar objects constitutes the second part of the First Byurakan Survey and is a natural continuation of it. For this second program, at the present time, a catalogue of 1103 blue objects has been built (see Cat. II/223). In a series of 14 papers, referenced in the "References" section below, have been published lists of 1000 late M type and carbon stars, selected on the FBS plates. We have revised and updated this 14 lists with the new data from recently published optical and infrared catalogs to give access to all available data. As a result, the catalog of the First Byurakan Survey (FBS) Late Type Stars, was compiled. In this catalogue are presented high accurate coordinates, proper motions, spectral, photometric and infrared dates about of 995 FBS late M type and carbon stars. Are given cross-identifications of FBS late type stars with their counterparts from the most popular catalogs (2MASS, USNO-B1, NOMAD, UCAC2, GCVS4.2, NSVS, ASAS, IRAS PS and IRAS FS). On the base of 2MASS (J-K) color indices were determined a luminosity classes for 988 of them. For the 55 stars were determined a spectral classes, and for the another 129 were determined a spectral subclasses on the base of DFBS (http://byurakan.phys.uniroma1.it/) These data were not presented in original lists.

Note (1): Coordinates are given according to UCAC2 (I/289). If the star is not present in UCAC2 coordinates are from NOMAD (I/297). Note (2): Spectral classification origin as follows: 1 = spectral class and subclass both from original papers. 2 = spectral class from original papers, subclass was determined by us from DFBS (http://byurakan.phys.uniroma1.it/) 3 = spectral class and subclass both was determined by us from DFBS (http://byurakan.phys.uniroma1.it/)

An independent check of the data (Cecile Loup, CDS) revealed many inconsistencies (see file "comments.htx"), especially in the luminosity and spectral classification, but also with cross-identification made independently by B. Skiff. * 22-Jun-2009: URL of the Digitized First Byurakan corrected (from 141.108.1.227 to byurakan.phys.uniroma1.it)
