Metallicity of Globular Cluster M13 from VI CCD Photometry
From the VI images of M13, obtained by using 2K CCD camera and the BOAO 1.8m telescope, we derive the (V-I)-V CMD of M13. From the shapes of red giant branch, the magnitude of horizontal branch, and the giant branch bump on the constructed CMD, we determined the metallicity of the globular cluster t...
