 \subsubsection{Structure of the analysis}
-******* to be documented *********
+The analysis package now deals with Gaspard trackers including different shapes.
+The main analysis program is the \$NPTool/NPAnalysis/Gaspard/src/Analysis.cc
+file where the user is in charge to code the specific functionalities he is
+interested in. This includes to treat cases with multiplicity greater than one,
+calculate the excitation energy, check the effect of beam tracker detector
+positioning resolution, ...
+
+However, all the basic treatments of the analysis are done in \$NPTool/NPLib/GASPARD.
+These basic treatments calculate the total energy deposited in the telescope and
+associate for each pixel number the cartesian coordinates of the pixel middle.
+
+The structure in \$NPLib/GASPARD is very similar to the NPSimulation structure
+for Gaspard. The GaspardTracker.\{h,cxx\} class derives from the VDetector class
+and holds ($i$) the GaspardTrackerData object to be analysed, ($ii$) the
+GaspardTrackerPhysics object with the results of the basic treatement and ($iii$)
+a map which associates the detector number read in the geometry file with a pointer
+to the GaspardTrackerModule class. In this way a Gaspard tracker geometry with any 
+kind of shapes is analyzed correctly. Each available shape (square, trapezoid, annular,
+dummyshape, ...) has its own class GaspardTracker*Shape*.\{h,cxx\} deriving from 
+the GaspardTrackerModule class. Each class basically applies the same stripping scheme 
+as defined in the simulation in order to obtain the cartesian coordinates of the center 
+of each pixel. Each class have its own treatement method to calculate the total energy
+deposited in each module.
+
+
+IMPORTANT NOTE: for the moment, only multiplicity one are considered.
