\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.
