We show how to remove uncertainties from these measurements and increase their sensitivity by measuring CP-conserving phases at a charm factory.10 page postscript file, postscript file also available through http://w4.lns.cornell.edu/public/CLNSHigh Energy Physics - ExperimentHigh Energy Physics - Phenomenologytext
