 // MHAlpha
 //
-// Create a false source plot. For the Binning in x,y the object MBinning
-// "BinningFalseSource" is taken from the paremeter list.
-//
-// The binning in alpha is currently fixed as 18bins from 0 to 90deg.
-//
-// If MTime, MObservatory and MPointingPos is available in the paremeter
-// list each image is derotated.
-//
-// MHAlpha fills a 3D histogram with alpha distribution for
-// each (derotated) x and y position.
-//
-// Only a radius of 1.2deg around the camera center is taken into account.
-//
-// The displayed histogram is the projection of alpha<fAlphaCut into
-// the x,y plain and the projection of alpha>90-fAlphaCut
-//
-// By using the context menu (find it in a small region between the single
-// pads) you can change the AlphaCut 'online'
-//
-// Here is a slightly simplified version of the algorithm:
-// ------------------------------------------------------
-//    MHillas hil; // Taken as second argument in MFillH
-//
-//    MSrcPosCam src;
-//    MHillasSrc hsrc;
-//    hsrc.SetSrcPos(&src);
-//
-//    for (int ix=0; ix<nx; ix++)
-//        for (int iy=0; iy<ny; iy++)
-//        {
-//            TVector2 v(cx[ix], cy[iy]); //cx center of x-bin ix
-//            if (rho!=0)                 //cy center of y-bin iy
-//                v.Rotate(-rho);         //image rotation angle
-//
-//            src.SetXY(v);               //source position in the camera
-//
-//            if (!hsrc.Calc(hil))        //calc source dependant hillas
-//                return;
-//
-//            //fill absolute alpha into histogram
-//            const Double_t alpha = hsrc.GetAlpha();
-//            fHist.Fill(cx[ix], cy[iy], TMath::Abs(alpha), w);
-//        }
-//    }
-//
-// Use MHFalse Source like this:
-// -----------------------------
-//    MFillH fill("MHAlpha", "MHillas");
-// or
-//    MHAlpha hist;
-//    hist.SetAlphaCut(12.5);  // The default value
-//    hist.SetBgmean(55);      // The default value
-//    MFillH fill(&hist, "MHillas");
-//
-// To be implemented:
-// ------------------
-//  - a switch to use alpha or |alpha|
-//  - taking the binning for alpha from the parlist (binning is
-//    currently fixed)
-//  - a possibility to change the fit-function (eg using a different TF1)
-//  - a possibility to change the fit algorithm (eg which paremeters
-//    are fixed at which time)
-//  - use a different varaible than alpha
-//  - a possiblity to change the algorithm which is used to calculate
-//    alpha (or another parameter) is missing (this could be done using
-//    a tasklist somewhere...)
-//  - a more clever (and faster) algorithm to fill the histogram, eg by
-//    calculating alpha once and fill the two coils around the mean
-//  - more drawing options...
-//  - Move Significance() to a more 'general' place and implement
-//    also different algorithms like (Li/Ma)
-//  - implement fit for best alpha distribution -- online (Paint)
+// Create a single Alpha-Plot. The alpha-plot is fitted online. You can
+// check the result when it is filles in the MStatusDisplay
+// For more information see MHFalseSource::FitSignificance
+//
+// For convinience (fit) the output significance is stored in a
+// container in the parlisrt
+//
+// PRELIMINARY!
