 for the orientation of the reference frame.
+This vector is made unitary internally in the code and thus only its direction matters here;

 \item [{\texttt{FACTOR\_FORCE\_SOURCE}}] This parameter specifies the magnitude of the force source.
 \item [{\texttt{COMPONENT\_DIR\_VECT\_SOURCE\_E}}] This parameter specifies the East component of 
 an arbitrary (non-unitary) direction vector of the force source.
