After testing the real N1 from the 4th KamLAND Data Release file, we got the following graph:







Comparing our N estimated from the P1estimate above with KamLAND’s N’1 obtained from the experiment, we got:







Chi square of the N between our estimate and the N observed:    



Chi square of the P between our estimate and the closest straight line of 0.44 without taking into account covariance:    



The above chi square with covariance:  




The results from the chi squares show that the P1estimate that we obtained through our method is a good fit for the appearance probability, while a constant probability is not.





Covariance Matrix of C









After KamLAND’s counts data was run through our method, we obtained appearance probabilities for 11 values of L/Eν without assuming an average L. Even though the errors appear large,

 the chi square accounting for covariance shows that not even the best fitted horizontal line of P(l) = 0.44 will fit the data obtained due to correlations between the data points.

Using the appearance probability graph obtained in this research, the predicted N matched KamLAND’s observed N based on the chi square.

We intend to apply the methods learned and used in this research to current and future experiments.
