1. final state study Jaewon Park University of Rochester MINERvA/Jupiter Group Meeting, Mar 14, 2007

2. 2 Single gamma (electron) calibration Nonlinearity at low energy was fake due to histogram binning error. (Same histog ram ranges were used for all energy) To avoid it, energy is summed for each e vent and divided by number of events.

3. 3 Reconstructed proton track starting vertex Require iTrk(i) = proton with true information Vertex-z varies in a range of 4.065cm Reconstructed vertex-z is shifted a little bit to downstream direction systematically

4. 4 mass in NC resonance events 5000 events were ge nerated and requires:  Select p+pi0 events  Using reconstructed primary vertex, pi0 mass distribution is preserved.
