WEXTER and ERAFITTER: two programs to fit M W at LEP2 using the best measurable kinematical variables

Abstract In this paper, we present two programs to fit M_Wat LEP2 using the best measurable kinematical variables. The theoretical probabilities of observing the final-state kinematical configurations are computed by integrating over the quantities that are not well measured. Therefore, an event-by-event kinematical reconstruction is avoided. M_Wis then determined through a maximum likelihood fit.
