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.
