 //
-// A tracklet consist of two ITS clusters, one in the first pixel
-// layer and one in the second. The clusters are associates if the 
-// differencies in Phi (azimuth) and Theta (polar) are inside 
-// a fiducial volume. In case of multiple candidates it is selected the
-// candidate with minimum distance in Phi. 
+// It retrieves clusters in the pixels (theta and phi) and finds tracklets.
