+\subsection{Local Maximum Search}
+This module implements searching for local maxima in a 2D histogram of 
+data. It is mainly intended for use at TRICS where initially
+reflections need to be searched for the determination of a UB
+matrix. The local maximum algorithm is a little more sophisticated
+then commonly used in that the window of the search is user definable,
+and a valid maximum has to have a certain steepness against the
+bordering points in order to be valid. Another validity test is a
+threshold which must be reached. All these enhancements should reduce
+the number of false maxima which may turn up as the result of horrible
+measurement statistics. 
+
+The position and intensity of a local maximum found can be refined further
+ with a center of gravity calculation within a given window including all
+ data points above a certain threshold expressed as a fraction of the local
+ maximums intensity.
+
+Again this module has a little data structure:
+ 
+@d lomaxdata @{
+	typedef struct __LOMAX {
+				  pObjectDescriptor pDes;
+	                          ObPar *pParam;
+				}LoMax;		          
+@}
+The fields are:
+\begin{description}
+\item[pDes] The standard object descriptor.
+\item[pParam] The parameters of this object.
+\end{description}
+
+The exported interface is simple: just the necessary functions for
+representing the object in the interpreter and a function which allows
+to use the local maxima search from another module. If the latter is
+ever needed.

+testLocalMaxima checks if point i, j is a valid local maximum. It
+returns true (1) if this is the case, or false (0) if this is not the
+case. The window parameter describes how much points shall be searched
+in each direction. 
+
+calculateCOG calculates the center of gravity for point i, j,. Points within a
+ sqaure window of size cogWindow are considered. Only points whose
+ intensity obeys I \gt I(i,j)*countour are used for the COG
+calculation. The position of the maximum (i,j) and its intensity are
+updated by calculateCOG.
