 // with Corning Blue and Corning Red values initialized for the MAGIC camera.
+// The values are valid for the camera after July 5, 2004.

+// The following plots display the distributions of the cornings: 
+// * The corning blue w.r.t. the pixel index:
+//   One can see the selection of pixels such that the highest corning blue values 
+//   are located towards the center of the camera.
+// * The corning red w.r.t. the pixel index:
+//   One can see that there is a population in the outmost ring of inner pixels
+//   with much lower corning reds. This characteristic is also valid for the 
+//   quantum efficiency in the green. 
+// * The corning blue vs. the corning red for the inner and outer pixels,
+//   respectively. The two populations are clearly visible for the inner pixels, 
+//   while for the outer ones, there is only one population with a bigger spread.
+//   The blue line marks the distinction of the two populations as used in 
+//   MCalibrationChargeCalc.
