Masses of globular clusters
Central velocity dispersions have been derived for 10 globular clusters from high dispersion (6.7A mm-1) coude spectra of the integrated light. Two methods were used. The first involved the comparison of the cluster spectra with star spectra convolved with an appropriate velocity distribution function. This is the method used often for velocity dispersion determinations from spectra of the integrated light of galaxies (e.g. Morton and Chevalier 1972). Fourier techniques were used in...[Show more]
