Description:
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 4.5x4.5°.The area
of 140 square degrees, under study, was overlapped by nine centers.
Kodak IIa-O, Kodak IIIa-J and Kodak IIIa-F plates were used.
A limiting apparent magnitude in V for the stars is between 12.5
photographic mag. and 15.0 photographic mag. for M stars.
The errors of our determinations are: ±0.6 for spectral subtype and
±0.5 for luminosity class.
The catalogue contains 558 objects with peculiarities in the spectrum
Ap, Am, BaII and composite spectrum stars, 86 emission stars O, B, M
and objects with Hα-emission as well as 453 M and 36
C-stars.Among 558 peculiar stars an overwhelming majority, namely 549,
are first found.
The stars in the Catalogue are arranged in the order of increasing
right ascension. The stars are numbered according to zones of 1°
in declination. The printed catalogue is provided with suitable
stellar charts 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. Clusters NGC 2168, NGC 1969 and OLC 0436 Whose sites in the
charts are denoted with the circles, are supplies with the charts
reproduced from relatively large-scale plates taken on the meniscus
telescope.

Note on ID: Each star is designated by 2 numbers separated by a blank
"DD NNN", where:
D = Declination zone (degrees)
N = Running number within the zone.
Note on SpT: the spectrum is formatted as:
1 = (byte 54): spectral temperature class
2 = (byte 55): spectral temperature subclass
3 = (byte 56): peculiarity
4 = (byte 57-59): luminosity class
7 = (bytes 60): '-' if luminosity class is uncertain
8 = (byte 61): '+' is spectrum is double
9 = (byte 62-63): secondary spectrum, if existing
