Scientific paper

The distributions of globular clusters in the spaces of basic physical parameters are considered using a cluster analysis method. The Euclidean distance between clusters in the corresponding space is used as the similarity measure. Several classification variants are proposed; in some cases, it is due to the dependence of the cluster properties on the distance from the Galactic center. The classes identified are not isolated but go from one to another continuously.
