- Double tag efficiencies, yields from data, and peaking background
expectations for $\Dz\Dzbar$ events. The efficiencies were
estimated with and without FSR to determine the size of the effect
of FSR. The entries in the column labeled Background are the
number of events in the signal peak produced by non-signal events;
estimation of these values is described in \Sec{sec:backgrounds}.
The quoted yields include these background events.
