Popis: |
In the muon (g - 2) experiment at Brookhaven National Laboratory, the spin precession frequency omega(a) is obtained from a standard chi(2) minimization fit applied to the time distribution of decay electrons. The unusually high accuracy (similar to 0.5 ppm) of the experiment puts stringent requirements on the quality of the fit and the level of understanding of the statistical properties of the fitted parameters. We discuss the properties of the fits and their implications on the derived value for omega(a), including estimates of the effect of an imperfect fit function, methods of including additional external information to reduce the error, the effects of splitting the data into many smaller subsets of data, applying different weighting methods to the data using energy information, and various tests of data suitability.
