Beginning of ReadMe : III/271 Spectral Classes in Kapteyn areas 68-91 (Chargeishvili+, 2000) ================================================================================ Catalogue of Spectral and Luminosity classes of 3914 stars in Kapteyn areas 68-91. Chargeishvili K.B., Bartaya R.A., Kharadze E.K. <Bull. Abastumani Astrophys. Observ. 75 (2000)> =2000AbaOB..75...93C =2013yCat.3271....0C ================================================================================ ADC_Keywords: Selected areas ; Spectral types Description: The present catalogue is the third one of the four catalogues published according to programme of Abastumani Astrophysical Observatory of a massive two-dimensional MK classification of stars in 115 kapteyn Select Areas (KA) of Northen Sky (Bartaya, 1983, Cat. III/112; Bartaya, Kharadze, 1992, Cat. III/270). The catalogue lists the spectral types and luminosity classes for 3914 stars in 24 Kapteyn areas 68-91 through the declination circle of 0deg. The catalogue is compiled on the basis of the spectral data obtained with the 70-cm meniscus telescope of Abastumani Astrophysical Observatory using the 8deg objective prism (dispersion 166AA/mm near Hgamma; in the short-wave region, the spectrum extends up to 3500AA). The field of the meniscus telescope is 4.5degx 4.5deg. The photo material is taken on Kodak IIa-O, hyper-sensitized Kodak IIIa-J and in order to detect also Halpha emission stars and M, S, C type stars in the surveyed KA's, hyper-sensitized Kodak IIIa-F plates were also taken. A limiting apparent magnitude in V for stars in question is 12.5 photographic mag. and for M ones - 15.0 mag. The data for all KA's are uniform not only in the sense of classification accuracy (the whole classification is done by one person - the author of the present catalogue), but also in the sense of penetration. The errors of our determinations are: +/-0.6 for spectral subtype and +/-0.5 for luminosity class. The stars in the KA's are arranged in the Catalogue by increasing right ascension. The stars are numbered according to zones of 1deg in declination. The printed catalogue is provided with suitable stellar charts for separate KA's reproduced from the Lick Catalogue. The reference system on the charts refers to 1950 epoch and it is plotted according to the Smithsonian Astrophysical Observatory (SAO) catalogue.
