A previous investigation of the virialization of isolated pairs of galaxies, by testing the end product of the N-body simulations of Efstathiou and Eastwood, is extended to include all pairs, regardless of isolation. It is found that the nonisolated pairs do not satisfy the classical virial theorem as well as isolated pairs, but masses can be estimated to an accuracy of factors of 1.5 for the Ω0 = 0.1 model and 2 for the Ω0 = 1.0 model, over a range of separations 25
