A New Analysis in the Field of the Open Cluster Collinder 223
The present study of the open cluster Collinder 223 (Cr 223) depended greatly on the photoelectric data of Claria and Lapasset. We use the data in conjunction with the AAO/DSS1 image of the cluster in a re-investigation to improve the main parameters of Cr 223, including the stellar density, the position of the cluster's center, the cluster's diameter. Its luminosity function, mass function, and total mass are also estimated.
