+ @brief FMD reconstruction
+*/
//____________________________________________________________________
//
-// This is a class that constructs AliFMDMult (reconstructed
-// multiplicity) from of Digits
-//
-// This class reads either digits from a TClonesArray or raw data from
+// This is a class that constructs AliFMDRecPoint objects from of Digits
+// This class reads either digits from a TClonesArray or raw data from
// a DDL file (or similar), and stores the read ADC counts in an
-// internal cache (fAdcs).
-//
-// From the cached values it then calculates the number of particles
-// that hit a region of the FMDs, as specified by the user.
-//
-// The reconstruction can be done in two ways: Either via counting the
-// number of empty strips (Poisson method), or by converting the ADC
-// signal to an energy deposition, and then dividing by the typical
-// energy loss of a particle.

-// AliFMDReconstructor acts as a manager class. It contains a list of
-// AliFMDMultAlgorithm objects. The call graph looks something like
-//
+// internal cache (fAdcs). The rec-points are made via the naiive
+// method.
