| 28 | // Class for otimizing the disp parameters. For more details see
|
|---|
| 29 | // MJOptimize.
|
|---|
| 30 | //
|
|---|
| 31 | // MJOptimizeDisp minimzes the width of the Theta^2 distribution by
|
|---|
| 32 | // minimizing <Theta^2> (the RMS^2 of Theta^2), while Theta^2 is
|
|---|
| 33 | // calculated as:
|
|---|
| 34 | // Theta^2 = d^2 + p^2 - 2*d*p*cos(a)
|
|---|
| 35 | // with:
|
|---|
| 36 | // d: MHillasSrc.fDist [deg]
|
|---|
| 37 | // p: Disp as calculated by the given rule, eg: [0] (a constant)
|
|---|
| 38 | // a: MHillasSrc.fAlpha [rad]
|
|---|
| 39 | //
|
|---|
| 40 | // Example:
|
|---|
| 41 | // --------
|
|---|
| 42 | // MJOptimizeDisp opt;
|
|---|
| 43 | // opt.SetDebug(2);
|

|
|---|
| 45 | // opt.SetNumEvents(20000);
|
|---|
| 46 | // opt.EnableTestTrain();
|
|---|
| 47 | // opt.AddParameter("1-(MHillas.fWidth/MHillas.fLength)");
|
|---|
| 48 | // opt.SetParameter(0, 1, 0, 2);
|
|---|
| 49 | // char *r = "[0]*M[0]"; //Rule to calculate disp
|
|---|
| 50 | // MStatusDisplay *d = new MStatusDisplay;
