Official plots (Boyd/Walter/Ishida) *Event Rate (Ishida) *Standard histograms and neutrino spectrum (Walter/Boyd) Official plots are almost finished. Please send comments. 2. Analysis report *Park studied nQE events with d-theta>40deg in MRD3d sample. Fraction of proton and pion is about 6 to 4. He noticed a small bump at 60deg and scanned those events. They are caused by wrong x-y combinations, multi-track acitivities around the vertex or bundle events. These events tend to happen downstream. *Park also studied 2-hit tracks. He finds some false tracks at theta=0. He scanned those events and found that they are caused by a big cluster mainly. The improvement of overlap filter has been in one of our job lists, but we need it very soon. *Ishida wants to improve pulse height corrections by adjusting the gain factors for each sheet. He is looking into the radial corrections which may be 10% effects. He is interested in contained events and NC events. *We will set up a new bank which includes the info of some variables containing Kalman fit, track length, N-pix, 2-hit tracks (our official use = 3-hit tracks) etc, before starting a next analysis. *Iwashita will work on the event selection and event rate estimation for the next few months. *BJK will work on 2-track analysis that Park is doing and develope a vertex and track reconstruction by working with Park. //
