Histogram Monitoring

In monitoring Raw hits per Wire Multiplicity histograms a variation of the technique described in the section on Defining Changing Histograms is used. A Kolmogorov test is carried out on each bin of the histogram, as well as on its overall shape. Sample histograms must have significant differences in more than one bin (by default a False Alarm Probability of less than 1×10 ^-4), and in their overall shape (a default False Alarm Probability of less than 1×10^-3). Those histograms meeting both of these criteria will be tagged as changing.
