The interstellar reddening in the direction of four low-latitude globular clusters.
Abstract
Photometry (uvby ) of 131 early-type stars selected by objective-prism spectroscopy or from the HD catalog is used to determine color excesses in the directions toward the metal-rich globular clusters NGC 6304, NGC 6352, and NGC 6441, as well as toward the peculiar globular NGC 6656 (M 22). Key words: photometry-uvbyfi, DDO - interstellar reddening - globular clusters
