+// variable fit, the following fits are performed:
+//
+// 0: No fit, simply draw the projection
+// 1: Single Gauss (for distributions flat-fielded over the whole camera)
+// 2: Double Gauss (for distributions different for inner and outer pixels)
+// 3: Triple Gauss (for distributions with inner, outer pixels and outliers)
+// 4: flat         (for the probability distributions)
+// (1-4:) Moreover, sectors 6,1 and 2 of the camera and sectors 3,4 and 5 are 
+//        drawn separately, for inner and outer pixels.
+// 5: Fit Inner and Outer pixels separately by a single Gaussian 
+//                 (only for MAGIC cameras)
+// 6: Fit Inner and Outer pixels separately by a single Gaussian and display 
+//                 additionally the two camera halfs separately (for MAGIC camera)
