In order to test normalization stuff I made a few plots:
(all for normal hierarchy (sin^2 (2th13)=0.01)

Here is usual one where I used     -MC method for beam nue background
                                                  -and T2K method for overall BG normalization

 

Here is usual one where I used     -MC method for beam nue background
                                                  -and normalization for overall BG computed from 1st principles
                                                       (This factor is 2.8 smaller than the T2K number
                                                             as explained over there)

Here is usual one where I used     -Spectrum method for nue background
                                                       (spectrum method for nue background is kind of described
                                                        over there on Nov10th 2006, but I'll do a better job soon)

                                                  -
and normalization for overall BG computed from 1st principles

For comparision here is the FNAL plot for the same oscillation parameter.

Finally here is a plot to just compare the two way of dealing with the beam nue background.
I know the color labelling is wrong for the beam nue using MC method, but here it is:
small beam nue = MC method (label should be green)
big beam nue  =Spectrum method



How to run oscillation code:

First is Okumura-san README file (with some of my modfications)



Spectrum plots:

Black dots: signal with detector effect
Red line: signal without detector effect
Green: Background beam nu_e
Purple: Background NC
Blue: Bakcround mis-ID nu_mu

Here is a plot which show the how the signal change when I include detector effects:
(energy smearing and likelihood efficiency)

Red= without detector effect, Black= with

I also made a plot for 2.5 OA sin^2(2th13)=0.1 but delta=0

Contour plots:

Black=Kamkioka only
Red=Kam+Kor OA1
Green=Kam+Kor OA15
Blue=Kam+Kor OA2 
Yellow=Kam+Kor OA2.5

Bug found on August 22nd, background was overestimated for Kamioka for small OA.
