+\section{Gaussian}
+
+Choosing the {\tt ADMBase} parameter {\tt initial\_data} to have the 
+value {\tt Constraint violating gaussian} creates initial data with the
+form
+\begin{eqnarray*}
+g_{xx} = g_{yy} = g_{zz} &=& 1 + A \exp \left(\frac{-(r-r_0)^2}{\sigma^2}\right)
+\\
+g_{xy} = g_{xz} = g_{yz} &=& 0
+\\
+K_{ij} &=& 0
+\end{eqnarray*}
+where the size and shape of the Gaussian is specified by parameters, $A$={\tt amplitude}, $r_0$={\tt radius} and $\sigma$={\tt sigma}.
