beam-position-3C1(6/7).eps:
	Polarization as a function of beam position at 3C16 or 3C17.
	Runs 44576-44591 constituted a special study where the beam
	was moved in x and y +/- 1 mm.  No dependence on beam position
	was discovered.

polarization-eng-run.eps:
	All polarization measurements performed during the engineering
	run (except runs 44558 and 44560 from tests with Hall A
	laser).  No correction for residual transverse polarization
	was performed.  Prior to 14 December 2002 the Wien angle was
	set such that there was approximately 5% transverse
	polarization.

polarization-wien-corrected.eps:
	Same as above except that a correction was applied such that
	the total polarization is shown, not just the longitudinal
	polarization.

polarization-hallA-laser.ps:
	Shows data from early in the engineering run.  Purpose of the
	study was to see the effects of Hall A bleed through when the
	attenuator was used to set the beam current to Hall C.  Hall C
	beam current was set to approximately 1 uA and runs taken with
	and without the Hall A laser on (set to 100 uA beam current).

polarization-20021216.eps:
	Polarization data taken on 12/16/2002 meant to measure the
	polarization during the month of December.

polarization-20030123.eps:
	Polarization data taken on 01/23/2003 to measure the
	polarization during physics data acquisition.  Dave Gaskell
	discovered that the beam had moved at 3C12 during run 44654.
	This run also had (perhaps) abnormally low polarization.

ihwp.ps:
	Polarization data taken immediately before and after the state
	of the insertable half wave plate (IHWP) was changed.

laser_phase.ps:
	Polarization data during studies of the G0 laser phase.  The
	phase was varied and runs taken.  Other halls had observed a
	fall off in polarization at the extrema of laser phase
	settings.  That was not observed here, but we may not have
	gone far enough out to have seen it.

moller_results.ps:
	Summary of results on IHWP state, target thickness, and
	varying slits vs. varying attenuator with Hall A beam off.

moller_results_all.ps:
	Data from early in Moller commissioning.  High statistics on
	polarization vs. beam current.

moller_results_all-44568.ps:
	Same as above except run 44568 is removed.  Improved
	statistics of distributions.

summary-gzero.dat:
	File containing polarization data from all engineering run
	Moller runs.
