The extraction of neutrino oscillation parameters from the ratio of rates ( nu _ed to e⁺nn)/( nu d to nu pn) is considered in the context of oscillations proposed to account for previous reactor data. The possibility that only nu _e, nu _mu oscillations occur is shown to be barely compatible with present limits on nu _mu to nu _e transitions. Predictions for nu _e, nu _mu to nu _tau oscillations are made for future accelerator experiments.
