CCD photometry of the Globular Cluster NGC 6093
  In this paper we present photometric CCD observations of the globular cluster
NGC 6093 (M80) in filters B, V , R and I. We produce the colour-magnitude
diagrams for this object and obtain values for its metallicity [Fe/H],
reddening E(V-B), E(V-I) and distance modulus (m - M)_0.
