+/**
+ * This is a routine which calculates automatic windows for RITA's
+ * monochromatic window mode. In this mode data from 9 analyzer blades 
+ * is displayed on the detector. RITA needs the windows in which to 
+ * sum the contributions of each detector blade. The algorithm to find 
+ * them goes like this:
+ * 1) the HM is summed in y, resulting in a 1D histogram
+ * 2) In the 1D histogram peaks are located.
+ * 3) For each peak from 2, the COG is calculated to get a good peak
+ *    center
+ * 4) The window is the peak center +- 9 bixels.
