1  AHARMIM 2008 reports the results from SNO Phase III measurement using an array of ${}^{3}\mathrm {He}$ proportional counters to measure the rate of NC interactions in heavy water, over the period between November 27, 2004 and November 28, 2006, corresponding to 385.17 live days. A simultaneous fit was made for the number of NC events detected by the proportional counters and the numbers of NC, CC, and ES events detected by the PMTs, where the spectral distributions of the ES and CC events were not constrained to the ${}^{8}\mathrm {B}$ shape.
2  AHARMIM 2005A measurements were made with dissolved NaCl (0.195$\%$ by weight) in heavy water over the period between July 26, 2001 and August 28, 2003, corresponding to 391.4 live days, and update AHMED 2004A. The $\mathit CC$, $\mathit ES$, and $\mathit NC$ events were statistically separated. In one method, the ${}^{8}\mathrm {B}$ energy spectrum was not constrained. In the other method, the constraint of an undistorted ${}^{8}\mathrm {B}$ energy spectrum was added for comparison with AHMAD 2002 results.
3  AHMAD 2002 reports the SNO result of the ${}^{8}\mathrm {B}$ solar-neutrino flux measured with charged-current reaction on deuterium, ${{\mathit \nu}_{{e}}}$ ${{\mathit d}}$ $\rightarrow$ ${{\mathit p}}{{\mathit p}}{{\mathit e}^{-}}$ , above the kinetic energy threshold of 5$~$MeV. The data correspond to 306.4 live days with SNO between November 2, 1999 and May 28, 2001, and updates AHMAD 2001 results. The complete description of the SNO Phase I data set is given in AHARMIM 2007 .
4  AHMAD 2001 reports the first SNO result of the ${}^{8}\mathrm {B}$ solar-neutrino flux measured with the charged-current reaction on deuterium, ${{\mathit \nu}_{{e}}}$ ${{\mathit d}}$ $\rightarrow$ ${{\mathit p}}{{\mathit p}}{{\mathit e}^{-}}$ , above the kinetic energy threshold of $6.75$ MeV. The data correspond to 241 live days with SNO between November 2, 1999 and January 15, 2001.
