Description
This report lists the final, best estimate of the target polarization P{sub T} as a function of time for all of the periods during which scattering data were (or may have been) collected. The information under ``RUN`` refers to {Delta}{sigma}{sub L}-runs. The notation ``sfs`` stands for ``start of frozen spin,`` ``efs`` for ``end of frozen spin,`` ``{yields} la`` for ``go to large-aperture`` target magnet position, and ``nla`` for ``not large-aperture`` position, i.e., the target magnet is in ``polarizing`` position. Where the ``NOTE`` column is blank it means that all standard frozen-spin conditions were in effect: the target temperature was reduced and the magnet was in large-aperture position. The timing marks were developed on the basis of three criteria: (1) the availability of direct NMR data, (2) the inclusion of major Target and Run boundaries, and (3) the arbitrary inclusion of enough ``minor`` Run boundaries to shorten large timing gaps. The sign of the P{sub T}-values is given in the NMR convention: (+) corresponds to predominant occupation of the Zeeman ground state (the ``thermal`` NMR-signals are considered positive). Since the target magnet field pointed upstream, (+) corresponds to target spin antiparallel to the beam momentum. The estimated uncertainty on P{sub T} is {plus_minus}6.5% (2{sigma}), and the estimated uncertainty on the ratio of values for the two signs of polarization, P{sub T}(+)/PT({minus}), is {plus_minus}4.3% (2{sigma}).
