The Preliminary Results of Near Infrared Occultation
Not Available

Photoelectric V and (B-V) for McCuskey stars near the Galactic anticenter
V and (B-V) for 135 stars near the Galactic anticenter were obtained.The ultimate purpose of the study is to establish accurate colors which,in conjunction with DDO-derived spectral and luminosity classes, willenable interstellar absorption correction. Ninety-four of these starsalso have been observed by McCuskey for a stellar density analysis ofthe Galactic anticenter. The specific objective here is to establish therelationship between the presented photoelectric and McCuskey'sphotographic colors and magnitudes. Small but significant systematicdifferences exist between the two systems. These differences, ifuniversal for McCuskey's entire sample, increase his distances by about20 percent and decrease his densities by about 40 percent.

The stellar distribution in the galactic anticenter.
