1  AOKI 1994 measures $\xi \mathit P_{\mu }$ =$-0.9996$ $\pm0.0030$ $\pm0.0048$. The above limit is obtained by summing the statistical and systematic errors in quadrature, normalizing to the physically significant region ($\vert \xi \mathit P_{\mu }\vert <1$) and assuming that $\xi $=1, its maximum value.
2  Assumes $\xi $=1.
