1
Previously we used the global fit result from BURKARD 1985B in OUR AVERAGE, we now only include their actual measurement. BURKARD 1985B measure ${{\mathit e}^{+}}$ polarizations P$_{T_{1}}$ and P$_{T_{2}}$ versus ${{\mathit e}^{+}}$ energy.

Global fit to all measured parameters. The fit correlation coefficients are given in BURKARD 1985B.
