“…The relevant equations and methods have been described previously [52]. In particular, it has been shown that, with suitable algebra, instrumental asymmetries cancel to first order when the beam spin is Hipped from spin up (+) to down ( -).…”

“…As in previous experiments [45,46,52] the standard electronic trigger included all seintillators in the magnetic spectrometer. It is conceivable that the presence of the carbon in the Janus polarimeter could cause a systematic error by scattering events away from the back scintillator.…”

“…The uncertainties reported for the previous measurements and the overall systematic uncertainty of the target polarization measurement are the main contributors to the systematic uncertainty listed in each column. The systematic uncertainties in the beam ( -1% [19]) and scattered particle's ( -2'%%uo [20]) polarization measurements are not included (see text). were not used in these tests because of the low efficiencies of these chambers (a valid trajectory through each chamber system that supplied any histogram used in the tests discussed above was a prerequisite).…”

“…The uncertainties in these previously measured quantities and the overall uncertainty in the target polarization ( -5% ) are included in the systematical uncertainties reported in Tables I-III. However, the systematical uncertainties in the beam polarization measurement [19] ( -1%) and the scattered particle's polarization measurement [20] (-2%) are not included in the values given in Tables I -III. These should be added to the total uncertainty.…”
