摘要：

We generalize the pull approach to define the chi(2) function to the analysis of the data with correlated statistical errors. We apply this method to the analysis of the Sudbury Neutrino Collaboration data obtained in the salt phase. In the global analysis of all the solar neutrino and KamLAND data we find the best fit (minimum chi(2)) values of neutrino parameters to be tan(2)theta(12)similar to0.42 and deltam(12)(2)similar to7.1x10(-5) eV(2). We confirm that the maximal mixing is strongly disfavored while the bounds on deltam(12)(2) are significantly strengthened.
