Magnitudes and spectral types in 5 galactic fields

This catalog was initially compiled at the Abastumani Observatory, containing photographic BV magnitudes and spectral classes for about 6000 stars up to V(lim)=13.0mag in five circular areas of 18{deg}^2^ located near the galactic-equator plane; the observations were made with the Abastumani 70cm Maksutov plus 4{deg} and 8{deg} prisms, yielding dispersions of 166 and 666 {AA}/mm at H-{gamma}. The compilation did not provide the star positions, and the magnitudes were found to have a rms scatter around 0.15mag, i.e. around 0.2mag for the B-V color index.

The charts were compared with the GSC1.1 (Cat. I/220) by B. Skiff (Lowell Observatory) thus providing accurate coordinates; B. Skiff also examined the cross-identifications with several other catalogues, and added the notes.
