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 В—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.
