Query: Neutrino oscillations and mixings with three flavors   Global fits to all data of candidates for neutrino oscillations are presented
in the framework of a three-flavor model. The analysis excludes mass regions
where the MSW effect is important for the solar neutrino problem. The best fit
gives $\theta_1 \approx 28.9^\circ, \theta_2 \approx 4.2^\circ, \theta_3
\approx 45.0^\circ, m_2^2 - m_1^2 \approx 2.87 \cdot 10^{-4} eV^2$, and $m_3^2
- m_2^2 \approx 1.11 eV^2$ indicating essentially maximal mixing between the
two lightest neutrino mass eigenstates.
