Abstract: 
The influence of unbound galaxies in the estimation of mass is tested in clusters of galaxies. Jacknife techniques have been used to assess the effect. It is shown that the virial and projected mass estimators are lowered by a factor of two at least when the samples are cleaned out for interlopers. © 1990 Kluwer Academic Publishers.
