A full angular analysis and search for CP violation in the angular distribution with the decays was performed. A broad invariant mass distribution accounted for all potential S-wave contributions leaking into the mass selection window. For B decays to light charmless particles, the hierarchy of decay amplitudes was expected. It was found that systematic errors in efficiencies were dominated by those in track finding and particle identification.
