Fig. 2.
Distributions of V magnitude (upper panel) and B–V color index (lower panel) for our targets. The blue and red stripes correspond to the Tycho and USNO-B1.0 magnitudes converted into the Johnson V magnitudes based on the relations of Høg et al. (2000) and Lépine & Shara (2005), respectively (see text for details). The white areas mark the V photographic (GSC II or YB6) ones.
