dc.descriptionThe problem of determination of the velocity anisotropy parameter (A) from star density profiles in globular clusters is considered. The calculations are performed for following clusters: M3, M12, M13, M15, M55, M56, Palomar 3, Palomar 14, NGC5139 (Omega Centauri) and NGC6535. We found that for most clusters is A=0. For M56 the parameter is calculated at limiting magnitudes B=21.5 and B=19.0 and we found A=0.8 and A=0.3 respectively. For Omega Centauri the anisotropy parameter is determined in three separate regions and we found: A=0 for central region, A=0.1 for middle region and A=0.3 for halo.
