+//  MPadSchweizer
+//
+//  This task applies padding such that for a given pixel and for a given
+//  Theta bin the resulting distribution of the pedestal sigma is identical
+//  to the distributions given by fHSigmaPixTheta and fHDiffPixTheta.
+//
+//  The number of photons, its error and the pedestal sigmas are altered.
+//  On average, the number of photons added is zero.
+//
+//  The formulas used can be found in Thomas Schweizer's Thesis,
+//                                    Section 2.2.1
+//
+//  There are 2 options for the padding :
+//
+//  1) fPadFlag = 1 :
+//     Generate first a Sigmabar using the 2D-histogram Sigmabar vs. Theta
+//     (fHSigmaTheta). Then generate a pedestal sigma for each pixel using
+//     the 3D-histogram Theta, pixel no., Sigma^2-Sigmabar^2
+//     (fHDiffPixTheta).
+//
+//     This is the preferred option as it takes into account the
+//     correlations between the Sigma of a pixel and Sigmabar.
+//
+//  2) fPadFlag = 2 :
+//     Generate a pedestal sigma for each pixel using the 3D-histogram
+//     Theta, pixel no., Sigma (fHSigmaPixTheta).
+//
+//
+//  The padding has to be done before the image cleaning because the
+//  image cleaning depends on the pedestal sigmas.
+//
+//  For random numbers gRandom is used.
+//
+//  This implementation has been tested for CT1 data. For MAGIC some
+//  modifications are necessary.
