-\section{Introduction}
-
-\subsection{Purpose of Thorn}
-
-Thorn IDAnalyticBH provides analytic initial data for vacuum black
-hole spacetimes. Initial data is provided for the 3-metric, extrinsic
-curvature, and if appropriate the conformal factor and it's spatial
-derivatives. The current initial data sets are for a single (Schwarzschild)
-black hole in isotropic coordinates, up to four Brill-Lindquist black
-holes, and any number of Misner-type black holes.

-\subsection{Technical Specification}

-\begin{itemize}
-
-\item{Implements} einsteinID
-\item{Inherits from} einstein
-\item{Tested with thorns} Einstein

-\section{Theoretical Background}
-
-
-\section{Algorithmic and Implementation Details}
-
-This thorn uses no special numerical methods, however two points
-are worth noting
-
-\begin{enumerate}
-
-\item{} The solution for Misner is obtained by summing a sequence
-
-\item{} The spatial derivatives of the conformal metric (when required)
- are calculated accurately using finite differencing of the
- exact solution by a very small spacing
-
-\end{enumerate}
-
-\section{Using the Thorn}
-
-This thorn can provide either the physical metric (use\_conformal=''no'')
-or the conformal metric and a conformal factor (and its spatial derivatives)
-(use\_conformal=''yes''). In general, the option use\_conformal=''yes'' should
-be used, since ????.

-\subsection{Discussion}
-
-
-
-\section{Interaction with Other Thorns}
-
-It is still to be decided how initial data should be supplied to
-for systems of evolution equations which use more or different
-variables to those in the einstein implementation
-
-\section{Future Development}
-
-Initial data sets which are missing from this thorn include
-
-\begin{itemize}
-
-\item{} Boosted single black hole
-\item{} Single black hole in harmonic spatial coordinates
-\item{} Single black hole in Eddington-Finkelstein coordinates
-
-\end{itemize}
