Spectral Classes in Kapteyn areas 2-43
Listed in IVOA Registry (Virtual Observatory)
The present catalogue is compiled on the basis of the spectral data obtained with the 70-cm meniscus telescope of Abastumani Astrophysical Observatory using the 8{deg} objective prism (dispersion 166{AA}/mm near H{gamma}; in the short-wave region, the spectrum extends up to 3500{AA}).
Description
We have confined ourselves to relatively bright stars (11.5 photographic mag.), whose spectra were obtained by us on Kodak IIa-O plates.
The spectra were broadened up to 0.4mm for an exposure of 20min. We succeeded to carry out a quite homogeneous mass two-dimensional MK classification, separating also peculiar stars. In order to detect also H{alpha} emission stars and M, S, C type stars in the surveyed Kapteyn areas (KA), panchromatic plates were also taken.

The catalogue contains 173 stars with peculiarities in the spectrum, in particular Ap, Am, BaII and composite spectrum stars, as well as 30 Be, 800 M-type, and a few S, R, N and WR stars. 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 areas were photographed both on Kodak IIa-O and ORWO 2P-3 plates with the same maximum exposure for each plate and they all cover areas of 4.5x4.5{deg}.
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 1{deg} 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.
