// Class AliCalcluster
// Description of a cluster of calorimeter modules.
-// A matrix geometry is assumed in which a cluster center
-// is identified by (row,col) and contains sig as signal
-// being the signal of the complete cluster.
-// Some info about cluster topology is provided in order
+// A 2D (matrix) geometry is assumed in which a cluster center is identified
+// by two integer indices (i,j), e.g. row and column indicators.
+//
+// The 1st signal value is the signal of the complete cluster.
+// This is the signal which is provided as default by invoking GetSignal().
+//
+// In case clustering/grouping of module signals was performed over several
+// rings around the center (see e.g. AliCalorimeter::Group), the following
+// additional information is provided by the various signal values :
+//
+// The 2nd signal value is the original signal of the central module.
+// The 3rd signal value is the total signal within the 1st (i.e. 3x3) ring of
+// modules around the cluster center.
+// The 4th signal value is the total signal within the 2nd (i.e. 5x5) ring of
+// modules around the cluster center.
+// Etc....
+//
+// Note : In case the cluster consists of only 1 module, then only the
+// 1st signal value will be present (for obvious reasons).
+//
+// Some dispersion info about cluster topology is provided in order
// to enable EM or hadronic cluster identification.
