The neutrino fluxes φ(E(${\nu }_{\mu }$)), φ(E(ν${¯}_{\mu }$)), and φ(E(${\nu }_e$)) in the Brookhaven Alternating Gradient Synchrotron wide-band beams have been determined by measurements of quasielastic interactions observed in a massive, high-resolution detector. These fluxes are accurately reproduced by Monte Carlo calculations.
