+\subsection{The \moc{sybilt} dependent records and sub-directories on a
+\dir{tracking} directory}\label{sect:sybiltrackingdir}
+
+When the \moc{SYBILT:} operator is used ($\mathsf{CDOOR}$={\tt 'SYBIL'}), the following elements in the vector
+$\mathcal{S}^{t}_{i}$ will also be defined.
+
+\begin{itemize}
+\item The main SYBIL model $\mathcal{S}^{t}_{6}$
+
+\begin{displaymath}
+\mathcal{S}^{t}_{6} = \left\{
+\begin{array}{rl}
+ 2 & \textrm{Pure geometry} \\
+ 3 & \textrm{Do-it-yourself geometry} \\
+ 4 & \textrm{2-D assembly geometry} \\
+\end{array} \right.
+\end{displaymath}
+
+\item Minimum space required to store tracks for assembly geometry $\mathcal{S}^{t}_{7}$ 
+
+\item Minimum space required to store interface currents for assembly geometry $\mathcal{S}^{t}_{8}$ 
+
+\item Number of additional unknowns holding the interface currents
+$\mathcal{S}^{t}_{9}$. These unknowns are used if and only if a current--based
+inner iterative method is set (with option \moc{ARM}).
+
+\end{itemize}
+
+The following sub-directories will also be present on the main level of a \dir{tracking}
+directory.
