fbsl.C          ROOT Macro computing the baseline for each pixel
        the function is declared as:
        int fbsl( 
        const char *datafilename    = "path-to-datafile.fits.gz",
          const char *drsfilename = "path-to-calibfile.drs.fits.gz",
          const char *TextOutFileName = "./appendfile.txt",
          const char *RootOutFileName = "./datafile.root",
          int firstevent      = 0,
          int nevents       = -1, 
          int firstpixel    = 0,
          int npixel        = -1,
          bool produceGraphic = false
        )

        the baseline and its rms is calculated for each pixel based on the data,
        given in the datafile.
        the results are appended to a textfile
        and the histograms ,which were used for caluculation, as well as some
overviews are stored in a root file.
        the 4 ints: firstevent, nevents, firstpixel, npixel can be used to calculate
only for a subset
        the last bool can be set to true, which will open 2 Canvases with overview
histograms.

        for automatic production of baseline analysis one can call this macro like
this:
e.g.
        root -l -q fbsl.C++'("/data00/fact-construction/raw/2011/10/26/20111026_036.fits.gz", "/data00/fact-construction/raw/2011/10/26/20111026_031.drs.fits.gz", "./fbsl.txt", "./20111026_036.root")'


        on the ISDC cluster, I used /opt/root5.18.x86_64/bin/root for testing.
