\caption{Events passing cuts in \on\ and \off\ regions for the Crab, listed by
  data set along with excesses, significance and \gr~rates. Various
  selection cuts described in Table~\ref{tab:selcuts} are also compared
  for data sets~I--III combined. The results using the ring-background
  model are given (denoted as Ring). The integrated flux
  from the Crab above 1~TeV is shown also, as described in Sect.~\ref{sec:flux}. The \rchisq\ for a~fit to a~constant flux for the data set is given, as is the percentage run-by-run rms~deviation in the~flux.}
