## Galactic globular cluster properties

### Description

This dataset provides astronomical and astrophysical properties of 147 globular star clusters in the Milky Way Galaxy obtained from the catalog of Webbink (1985). Properties include Galactic location, integrated stellar luminosity, metallicity, ellipticity, central surface brightness, color, and seven measures of dynamical state (core and tidal radius, concentration, central star density and relaxation time, central velocity dispersion and escape velocity). The sample is described in Appendix C.7 of Feigelson & Babu (2012) with statistical analysis in Chapter 8. It is useful to exercise techniques of multivariate analysis and regression.
