+tpeak.C ROOT macros to produce overlays of data around a found peak in a given
+window.

+int tpeak(
+  char *datafilename    = "data/20111016_013.fits.gz",
+  const char *drsfilename = "../../20111016_011.drs.fits.gz",
+  const char *OutRootFileName = "../analysis/fpeak_cdf.Coutput.root",
+  int firstevent      = 0,
+  int nevents       = -1,
+  int firstpixel      = 0,
+  int npixel        = -1,
+  bool spikeDebug = false,
+  int avg1    = 14,
+  int avg2    = 8,
+  int OverlayWindowLeft = 50,
+  int OverlayWindowRight = 150,
+  int verbosityLevel = 1, // different verbosity levels can be implemented
+here
+  bool ProduceGraphic = true
+  )
+
+call it like this, if you want to overlay a certain number of peaks for a
+single channel
+tpeak("data/20111029_017.fits.gz","data/20111029_013.drs.fits.gz","test.root",0,1000,333,1,true,0,0,50,150,1,true)
+
+set the first bool 'spikeDebug' to false in order to overlay quicker ... every
+50th event the canvas is updated.
+depending on what kind of peaks you like to detect the sliding average filters
+should be set to e.g. 14,8 for singles in a quiet G-APD pedestal run
+or 0,0 if you want to see just every thing that might be a signal...
+
+the window size 50,150 means .. 50 slices to the left of the maximum and 150
+to the right.
+
+there is a bit of cleaning included in the file, maybe you want to switch it
+off, then just search for the calls of these methods... 
+ removeMaximaBelow( *zXings, 3.0);
+ removeRegionWithMaxOnEdge( *zXings, 2);
+ removeRegionOnFallingEdge( *zXings, 100);
+
+and comment them out or play with the settings.
+
+they are defined in zerosearch.C, which is maybe a bad choice...
+
