+To inform {\tt MMVII} of the SysCo of some data, there are several methods:
 
 \begin{itemize}
 \item Some importations have an implicit SysCo, E.G. {\tt ImportInitExtSens} that suppose that RPC are always in WGS geographical coordinates in degrees.
 \item {\tt ImportOri} let you give the SysCo with {\tt SysCo} option.
 \item {\tt ImportGCP}: let you transform ground coordinates on-the-fly with {\tt ChSys} option.
-\item {\tt OriChSysCo} and {\tt GCPChSysCo}: let you transform Ori and ground points from one SysCo to an other.
+\item {\tt OriChSysCo} and {\tt GCPChSysCo}: let you transform Ori and ground points from one SysCo into an other.
 \end{itemize}
 
+\subsection{SysCo definition}
 The SysCo names to give to {\tt MMVII} commands can be:
 \begin{itemize}
 \item The name of a file in source sub-folder {\tt MMVII/MMVII-RessourceDir/SysCo} or in project sub-folder {MMVII-PhgrProj/SysCo}, without its extension.

+\item {\tt SysCo=LocalPanel} will set the SysCo to a local system named "LocalPanel", that will not be convertible into any other SysCo.

+\item {\tt SysCo=RTL*0.67451979*45.18899334*0*EPSG:4326} will set the SysCo to a local euclidian frame where origin is $0.67451979, 45.18899334, 0$ in EPSG:4326.
+\item {\tt SysCo=Toto} will use a project-defined SysCo if {MMVII-PhgrProj/SysCo/Toto.xml} exists. If not, "Toto" will be used as a libproj definition, and an error will occur.
+\item {\tt SysCo=GeoC} will set the SysCo to geocentric coordinates.

 Then every Ori and groumd measures can be transformed into this RTL frame to be able to keep maximal precision during bundle adjustment.
