On peculiarities of the red giant branch star distribution of the globular clusters with poor and middle metal abundance.
Abstract
The luminosity functions for the giant red branch were constructed for 11 globular clusters with low and average metallicity based on photographic photometry and published data. The luminosity range is about 3 m from the red giant branch tops. A generalized RGB luminosity function was obtained.
