A virial mass determination of the open cluster NGC 6494.
Abstract
Using the relative proper motions of 128 member stars of NGC 6494, a cluster mass of approximately 1300 M solar masses is estimated by application of the virial theorem. This value is found to be in excellent agreement with the 'directly' counted cluster mass of 1200 M solar masses.
