I would like to compair two histograms with the Kolmogorov-Smirnov test or some similar goodness of fit test. I know that chi squared and RMS are both avaliable as standard tests. Are either the K-S or Anderson-Darling avaliable in root. If so how do I access them? -- Stanley S.

I presume you will have to look around a bit, but it should be not too difficult to find. If needed, we can look later together. For now, I suggest we produce the two files and then discuss how to compare them. I will ask Rob to send us his script and we will take a close look.

I'll continue using jbel01. I'll have to look up how to tell different time ranges and could you explain what a KS test is?
