Notes. Cluster name, Plummer scale radius, median cluster-centric distance, axis ratio, position angle, age, and ratio of mean velocity to velocity dispersion. The errors on R₅₀, q, and PA were computed through 1000 bootstrap extractions of the 90% of the sample. We note that such analysis accounts only for fluctuations due to small statistics or outliers. Values obtained through a proper exploration and sampling of the parameter space, such as the one performed for R_Plummer, are thus more realistic.
