Table lists the contributions to the systematic error which were treated as fully correlated among the four data taking periods. One change with respect to previous publications is that in performing the parameter transformations to produce Table the parameters referring to the -interference have been fixed to their values. This was done to conform with the procedures employed by the other LEP experiments. Figure shows a comparison of the results with the Standard Model prediction for the fitted parameters in Table . Figures and show comparisons of the measured cross sections and asymmetries with the result of the Standard Model fit.
Figure displays the one standard deviation contours in the - plane.
