 The cGroup structure contains the information
 \begin{itemize}
 \item grouptype: The group type
-\item variabletype: The type of variables in the group
-\item staggertype: The type of grid staggering for arrays
+\item vartype: The type of variables in the group
+\item stagtype: The type of grid staggering for arrays
 \item dim: The dimension of variables in the group
-\item numvariables: The number of variables in the group
+\item numvars: The number of variables in the group
 \item ntimelevels: The number of timelevels for variables in the group
