+// PCA redesigned by Gustavo Conesa October 2002:
+// The way of using the PCA has changed. Instead of 2
+// files with the PCA, each one with different energy ranges
+// of application, we use the wide one (0.5-100 GeV), and instead
+// of fixing 3 ellipses for different ranges of energy, it has been
+// studied the dependency of the ellipses parameters with the
+// energy, and they are implemented in the code as a funtion
+// of the energy.
