The survival probabilities as a function of neutrino
energy. For each of the six best-fit globally acceptable neutrino
oscillation solutions, the viewgraph
shows the survival probability for electron type neutrinos as a
function of energy. The results are averaged over one year.

The relative CC recoil energy spectra for six
oscillation solutions. The viewgraph shows the rates,
(R(Ee),
predicted by different best-fit oscillation solutions as a function of
the electron recoil energy, Ee, divided by the rate predicted by the
standard solar model and no neutrino oscillations.

The neutral current to charged current double ratio.
The viewgraph shows, for a 5 MeV threshold for the CC
measurement, the predicted double ratio of Neutral Current to
Charged Current for different neutrino scenarios.
The error bars for the neutrino scenarios
represent the 99% C.L. allowed regions for the currently favored
neutrino oscillation solutions. The estimated experimental error bar
is shown on the far right.

The neutral current to charged current double ratio.
The viewgraph shows
the same ratio as in the previous viewgraph but for an 8 MeV CC threshold.
The error bars
represent the 99% C.L. allowed regions for the currently favored
neutrino oscillation solutions.
The combined 3
calculational and measurement errors are estimated to be
smaller than the size of the black dots indicating the best fit values.

The neutrino-electron scattering to charged current
double ratio. The viewgraph shows, for
a 5 MeV electron recoil energy threshold, the predicted double ratio
of Neutrino-Electron Scattering to Charged Current for different
neutrino scenarios. The error bars for the neutrino scenarios
represent the 99% C.L. allowed regions for the currently favored
neutrino oscillation solutions. The estimated experimental error bar
is shown at the far right.

The percentage difference between the night and the
day CC rates. The viewgraph shows for different neutrino scenarios the
percentage difference between the predicted CC rate in SNO at night
and the CC rate in the day. The
results were calculated with a CC threshold of 5 MeV for the total
electron recoil energy. The error bars
represent the 99% C.L. allowed regions for the currently favored
neutrino oscillation solutions.

The [NC]/[CC] double ratio versus the day-night
asymmetry. The viewgraph shows the fractional difference in percent of
the neutral current versus charged current double ratio, [NC]/[CC],
from the no oscillation value of 1.0,
versus the day-night difference, AN-D
in percent. The standard model value of
AN-D is 0.0.
For the six currently preferred oscillation solutions, the error bars
represent the 99% C.L. regions for acceptable fits to all the
available neutrino data. Estimated error contours for SNO are shown
at the 1, 2, 3, and 5 levels
relative to the no oscillation solution which lies at (0,0).
