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.
