Following the publication of the results from an analysis of the third phase of the experiment, and the recent release of a paper presenting a low energy threshold analysis of Phases I and II, the Sudbury Neutrino Observatory Collaboration is now performing a final joint analysis of the data collected during the entire experiment. The signal extraction process of this solar neutrino analysis is divided into two components: the measurements of 8B and hep signals. The 8B analysis combines the photomultiplier tube data from the three phases along with the results from a pulse shape analysis of the data from the neutral current detectors used during the third phase to provide the most accurate SNO measurement of the total 8B flux and the day/night energy-dependent electron neutrino survival probability. The hep analysis, which has always been statistically limited, has its sensitivity enhanced over previous measurements by the combination of the three-phase data set. The hep analysis uses the energy distortion at the end point of the data spectrum to extract the best hep flux measurement. With the new SNO results from the signal extraction process, two-flavour and three-flavour neutrino oscillation analyses are being performed with improved resolution on the oscillation parameters. An updated global fit combining all solar neutrino experiments will be presented as well.
