// MagicHillas.C
// =============
//
// This is a demonstration program which calculates image (Hillas +)
// parameters using as input a Merpp output file (raw data).
// All parameters are written to an output file called hillas.root. Also
// filles histograms are displayed.
// For the calculation an arbitrary signal extractor (MCerPhotAnal2/Calc)
// is used.
//

    // The tasklist is identified in the eventloop by its name
    //

    //
    // Use this if you want to change the binning of one of
    // the histograms. You can use:
    // BinningConc, BinningConc1, BinningAsym, BinningM3Long,
    // BinningM3Trans, BinningWidth, BinningLength, BinningDist,
    // BinningHeadTail, BinningAlpha, BinningSize, BinningDelta,
    // BinningPixels and BinningCamera
    //
    // For more information see MBinning and the corresponding
    // histograms

    //

    // for real adat files use MCerPhotAnal2 instead which also
    // calculates the pedestal.
    MCerPhotCalc ncalc;
    //
    //  Alternative photon calculation:
    //  Example: use only 2nd to 6th FADC slices for photon calculation:
    //
    //    const Float_t x[15]={0, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0};
    //    const TArrayF w(15,(Float_t*)x);
