Adopting the 3 neutrino framework, we present an updated determination of the
oscillation parameters. We perform a global analysis and develope simple
arguments that give essentially the same result. We also discuss determinations
of solar neutrino fluxes, capabilities of future experiments, tests of CPT,
implications for neutrino-less double-beta decay, beta decay, cosmology.Comment: 18 pages, 8 figures. Results compiled at page 1, table 1, fig.
