    (2016) Panko, Olena O.; Bajan, Katarzyna; Flin, Piotr; Gotsulyak, Alla; Панько, Олена Олексіївна; Панько, Елена Алексеевна
    Morphological types were determined for 247 rich galaxy clusters from the PF Catalogue of Galaxy Clusters and Groups. The adopted types are based on classical morphological schemes and consider concentration to the cluster center, the signs of preferential direction or plane in the cluster, and the positions of the brightest galaxies. It is shown that both concentration and preferential plane are significant and independent morphological criteria.
