Ratio should be investigated by each ? angle bin
1) Num. of ? bins 10, ? ? 10 o from 0 o
to 70 o due to statistics issue 2) Only study of
correlation between angles(?, f) 3) Pion momentum
can be corrected by f(?, f) 4) Finding and fix
the bug in the correction code ? expect
improve the both peak position and resolution 5)
Currently checking up the code with full stat.
