Abstract:
The spectral types and photographic magnitudes of 3340 stars brighter than
12m,5 were determined in an area of about 45 square degrees with the center
R.A.(1950) = 02h30m, Decl.(1950) = +58o00'. For Î, B, A and F stars the
colour indices were also found. The photographic magnitudes and color
indices were reduced to the (Â, V) system.
Description:
In first and second of the catalogue columns are presented the right
ascension and declination (epoch 2000.0) obtained for stars from
identification maps. The third column (first column in original catalogue)
- number of zone and also the star's number in this zone. In the following
columns may be found the spectral class, magnitude of the star and colour
index. The magnitudes for stars with note 1 were obtained from AGK2
catalogue. The spectral classes for O, B and A stars with luminosity
classes, magnitude of the star and colour index with note 2 were obtained
from Hiltner [1] catalogue. The spectral classes for M stars with
luminosity classes, magnitude of the star and colour index with note 3 were
obtained from Blanco [2] catalogue. Uncertain spectral classes, stellar
magnitudes and colour indices are marked « : ». The number according to BD
catalogue are presented in column 7. Last column are information from
catalogue note.

Note (1):
1. Magnitudes for stars were obtained from AGK2 catalogue;
2. Spectral classes stars with luminosity classes, magnitude of the star and
colour index were obtained from Hiltner's catalogue [1];
3. Spectral classes stars with luminosity classes, magnitude of the star and
colour index were obtained from Blanco's catalogue [2];
4. Only one component is visible.
5. In the Hiltner's catalogue this star have a V = 10m,52 and —V = 1m,08.
Probably this star a variability or mistake in the catalogue.
* The spectras with by marks cB0 may be spectral classes the O or B2 Ia, B2 Ib.
* The object +60 377 don't present in identification map.

This catalogue was be published in 20 Volume of "Izvestiya" the Crimean
astrophysical observatory (Krymskoj Astrofizicheskoj Observatorii). Scaning
and transformation of the print version for computer was accomplished by
Ludmila Filatova. The preview of star's coordinates from identification maps
was performed by Aleksey Sosnovskiy. Next step for search of star's
coordinates with errors checking, recordings, and data corrections was
accomplished by Maksim Gorbunov under the supervision of Roald E. Gershberg
and Aleksey A. Shlyapnikov. This work was supported by a grant of the RFFR
and Crimea Republic (No 16-42-910595).
