Description:
The present catalogue is the last 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.
The catalogue lists the spectral types and luminosity classes for 3880
stars in 23 Kapteyn areas 92-115 through the declination circle of
0°.
KA 95 was skipped because of poor quality of observational data. The
catalogue is compiled on the basis of the spectral data obtained with
the 70-cm meniscus telescope of Abastumani Astrophysical Observatory
using the 8° objective prism (dispersion 166Å/mm near Hγ;
in the short-wave region, the spectrum extends up to 3500Å). The
field of the meniscus telescope is 4.5°x4.5°. The photo
material is taken on Kodak IIa-O, hyper-sensitized Kodak IIIa-J and in
order to detect also Hα 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 - 15.0mag.
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 1° 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.

--------------------------------------------------------------------------------
Note on SA, IDz, IDn:
Each star is designated by 3 numbers separated by a blank "K Z N", where:
K = Kaptyen area number (between 92 and 115)
Z = Declination zone (sign, degrees)
N = Running number within the zone
Note on SpType:
the spectrum is formatted as:
0 = (byte 62): luminosity prefix (d g c) if any;
1 = (byte 63): spectral temperature class
2 = (byte 64): spectral temperature subclass
3 = (byte 65): peculiarity
4 = (bytes 66-68): luminosity class
7 = (byte 69): '-' if luminosity class is uncertain
8 = (byte 70): '+' is spectrum is double
9 = (byte 71): secondary spectrum, if existing
Note on BSD:
The Bergedorfer Spektral Durchmusterung was prepared by
Schwassmann A. and van Rhijn P.J., and published by the Hamburger
Sternwarte in Bergedorf between 1935 and 1953 in 5 volumes. Note that
only the second part of the BSD designation is stored in this column:
the Kapteyn Area number (the "SA" number) must be added in front of the
contents of this column to generate the complete BSD designation.
