It has been noted that the traditional spin-asymmetry $\frac{(p - m)}{(p + m)}$ plot is misleading about the uncertainty in the information contained in the spin-splitting. In particular, by dividing by the sum the error bars are amplified for (p,m) combinations that have greater uncertainty.
Alex G. has suggested that we offer another plot (instead?) of $\frac{(p - m)} {R_{\textrm{Fresnel}}}$, so that the error bars are less dependent on random fluctuations in the measured value (p + m) in the denominator.
