Double tag efficiencies, yields from data, and peaking background
expectations for $\Dz\Dzbar$ and Dp Dm 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.
