We present measurements of the time-dependent -violating asymmetries in decays based on decays collected with the BABAR detector at the PEP-II asymmetric-energy Factory at SLAC. We obtain the asymmetry parameters and , where the first uncertainties are statistical and the second systematic. These results are consistent with standard model expectations.
