A time-dependent angular analysis of pan id="mmlsi1" class="mathmlsrc">pan class="mathContainer hidden">pan class="mathCode">pan>pan>pan> decays is performed using data recorded by the LHCb experiment. The data set corresponds to an integrated luminosity of pan id="mmlsi16" class="mathmlsrc">pan class="mathContainer hidden">pan class="mathCode">pan>pan>pan> collected during Run 1 of the LHC. The CP -violating phase and decay-width difference of the pan id="mmlsi179" class="mathmlsrc">pan class="mathContainer hidden">pan class="mathCode">pan>pan>pan> system are measured to be pan id="mmlsi4" class="mathmlsrc">pan class="mathContainer hidden">pan class="mathCode">pan>pan>pan> and pan id="mmlsi5" class="mathmlsrc">pan class="mathContainer hidden">pan class="mathCode">pan>pan>pan>, respectively, where the first uncertainty is statistical and the second systematic.
