Abstract

We present new (V,V-I)-photometry of the metal-rich globular clusters NGC 5927, 6316, 6342, 6441 and 6760. The clusters show differential reddening up to mag, for which the CMDs are corrected via extinction maps. There are hints of a variation in the extinction law. Two different ways to determine the parameters metallicity, reddening and distance lead to consistent results. The metallicities of the clusters range between dex and the absolute reddening between mag. Taking the differential reddening into account leads to slightly increased distances. From the resulting parameters we conclude that the usual halo-disk-distinction in the system of globular clusters seems questionable.
