We re-examine MSW solutions of the solar neutrino problem in a two flavorscenario taking (a) the results on total rates and the electron energy spectrumfrom the 1117-day SuperKamiokande (SK) data and (b) those on total rates fromthe Chlorine and Gallium experiments. We find that the SMA solution gives thebest fit to the total rates data from the different experiments. One newfeature of our analysis is the use of the moments of the SK electron spectrumin a $\chi^2$ analysis. The best-fit to the moments is broadly in agreementwith that obtained from a direct fit to the spectrum data and prefers a $\Deltam^2$ comparable to the SMA fit to the rates but the required mixing angle islarger. In the combined rate and spectrum analysis, apart from varying thenormalization of the $^8$B flux as a free parameter and determining itsbest-fit value we also obtain the best-fit parameters when correlations betweenthe rates and the spectrum data are included and the normalization of the $^8$Bflux held fixed at its SSM value. We observe that the correlations between therates and spectrum data are important and the goodness of fit worsens whenthese are included. In either case, the best-fit lies in the LMA region.Comment: 17 pages, 4 figure
