\subsection{Contents of a \dir{intdetec} data structure}\label{sect:intdetecdir}

\vskip 0.2cm
The \dir{intdetec} data structure is used to store integrated detector positions and 
responses in a PWR. This object has a signature {\tt L\_INTDETEC}; it is created using
the \moc{IDET:} module.

\subsubsection{The state-vector content}\label{sect:devicestate}
\noindent
The dimensioning parameters $\mathcal{S}_i$, which are stored in the state
vector for this data structure, represent:

\begin{itemize}

\item  The first dimension of matrices {\tt COORD1}, {\tt COORD2} and {\tt COORD3}, representing
the maximum number of interpolation points for a single detector. $N_{\rm max} = \mathcal{S}_1$.

\item  The total number of detectors. $N_{\rm det} = \mathcal{S}_2$. 

\end{itemize}

\subsubsection{The main \dir{intdetec} directory}\label{sect:intdetecdir}
\noindent
The following records will be found on the first level of \dir{intdetec} directory:
