29// MHFalseSource
30//
31// Create a false source plot. For the Binning in x,y the object MBinning
32// "BinningFalseSource" is taken from the paremeter list.
33//
34// The binning in alpha is currently fixed as 18bins from 0 to 90deg.
35//
36// If MTime, MObservatory and MPointingPos is available in the paremeter
37// list each image is derotated.
38//
39// MHFalseSource fills a 3D histogram with alpha distribution for
40// each (derotated) x and y position.
41//
42// Only a radius of 1.2deg around the camera center is taken into account.
43//
44// The displayed histogram is the projection of alpha<fAlphaCut into
45// the x,y plain and the projection of alpha>90-fAlphaCut
46//
47// By using the context menu (find it in a small region between the single
48// pads) you can change the AlphaCut 'online'
49//
50// Each Z-Projection (Alpha-histogram) is scaled such, that the number
51// of entries fits the maximum number of entries in all Z-Projections.
52// This should correct for the different acceptance in the center
53// and at the vorder of the camera. This, however, produces more noise
54// at the border.
55//
56// Here is a slightly simplified version of the algorithm:
57// ------------------------------------------------------
58// MHillas hil; // Taken as second argument in MFillH
59//
60// MSrcPosCam src;
61// MHillasSrc hsrc;
62// hsrc.SetSrcPos(&src);
63//
64// for (int ix=0; ix<nx; ix++)
65// for (int iy=0; iy<ny; iy++)
66// {
67// TVector2 v(cx[ix], cy[iy]); //cx center of x-bin ix
68// if (rho!=0) //cy center of y-bin iy
69// v=v.Rotate(rho); //image rotation angle
70//
71// src.SetXY(v); //source position in the camera
72//
73// if (!hsrc.Calc(hil)) //calc source dependant hillas
74// return;
75//
76// //fill absolute alpha into histogram
77// const Double_t alpha = hsrc.GetAlpha();
78// fHist.Fill(cx[ix], cy[iy], TMath::Abs(alpha), w);
79// }
80// }
81//
82// Use MHFalse Source like this:
83// -----------------------------
84// MFillH fill("MHFalseSource", "MHillas");
85// or
86// MHFalseSource hist;
87// hist.SetAlphaCut(12.5); // The default value
88// hist.SetBgmean(55); // The default value
89// MFillH fill(&hist, "MHillas");
90//
91// To be implemented:
92// ------------------
93// - a switch to use alpha or |alpha|
94// - taking the binning for alpha from the parlist (binning is
95// currently fixed)
96// - a possibility to change the fit-function (eg using a different TF1)
97// - a possibility to change the fit algorithm (eg which paremeters
98// are fixed at which time)
99// - use a different varaible than alpha
100// - a possiblity to change the algorithm which is used to calculate
101// alpha (or another parameter) is missing (this could be done using
102// a tasklist somewhere...)
103// - a more clever (and faster) algorithm to fill the histogram, eg by
104// calculating alpha once and fill the two coils around the mean
105// - more drawing options...
106// - Move Significance() to a more 'general' place and implement
107// also different algorithms like (Li/Ma)
108// - implement fit for best alpha distribution -- online (Paint)
109// - currently a constant pointing position is assumed in Fill()
110// - the center of rotation need not to be the camera center
111// - ERRORS on each alpha bin to estimate the chi^2 correctly!
112// (sqrt(N)/binwidth) needed for WOlfgangs proposed caluclation
113// of alpha(Li/Ma)
114// - use the g/h-separation filters from the tasklists ("Cut1") as filters
115// two
