Abstract

Magnitudes and color indices in the Vilnius seven-color system were determined for 1752 stars down to V = 19.5 mag in the direction of the open cluster M29 (NGC 6913). The region is centered at RA = 20:24, DEC = +38:30 (J2000) and covers an area of 1.5 sq. deg. The photometric data are used to classify about 70% of stars in spectral and luminosity classes and peculiarity types.

Keywords: stars: photometry: Vilnius photometric system; stars: fundamental parameters, classification; Galaxy: open cluster (NGC 6913, M29)
