\begin{description}
\item[{\em qsec}]The calibration event handle\item[{\em dgm}]The event datagram\end{description}
\end{Desc}
\begin{Desc}
\item[Note:]The root contribution is opaque to the caller, so QSEC must handle the contributions within the root. There are two strategies one could use\begin{enumerate}
\item Call LSF\_\-scanContribtions and let it parse through them and invoke a user call back routine\item Do the scan by hand.\end{enumerate}
\end{Desc}
Initially I have opted for strategy \#1, but the second strategy makes detailed error checking easier. For example, if the sequence of the contributions is fixed, it is likely easier to do this when doing the scan by hand. \hypertarget{QSEC_8c_5cf6a83ceb47d157f035a1f9ab782131}{
