  All existing measurements of the solar neutrino flux are compared with the
predictions of the most recent solar model by Bahcall and Pinsonneault,
modified by introducing the hypothesis of neutrino oscillations with mass
differences large enough to render energy-independent any quantity observable
on earth. It is concluded that the data are consistent with this hypothesis and
that, at least for the time being, any energy-dependence of the solar neutrino
deficit must be regarded as just an attractive theoretical possibility, but not
as a compelling reality.
