A.K.Ichikawa, Kyoto univ.
We have just started not to be in a time blind with construction works.
Activity members come from KEK, Kyoto univ and Tokyo univ.
Systematic shifts on (sin22q23,Dm232) are evaluated with following systematic errors.
* Super-K intrinsic
Energy dependent non-QE/CCQE ratio, NC/CC ratio
energy scale and normalization (comes from FV, PID etc.)
For ne appearance, statistical and Super-K intrinsic error would be dominant. Still update of p.7 table with T2K off-axis flux is important to confirm this.
Robustness against the hadron production uncertainty will be checked.
En(Super-K) v.s. En(on-axis) will be made, too.
