Methods for mass estimation
Globular cluster
Globular cluster masses can be determined by observing the proper motion of nearby stars influenced by the cluster[1][2] or by estimating the cluster's relaxation time.[3]
Open clusters
The masses of open star clusters can be estimated by measuring the falloff of radial and tangential velocities of surrounding stars at a particular distance.[4]
