K2K Nov-Dec/2001 Official Plots

• Hit finding efficiency
  99Oct-01July BeamData (blue-bars) & CosmicRay-Data(dots) with newly tuned 2001 config MC (solid line).
• Tracking performance (Will be uploaded soon)

• Data to MC plots:
  We give figures in two ways: one with statistical errors only () and the other with muon energy scale error of +-3%. ( Emu -> Emu*(1+-0.03) ) (). When we show those plots, we point out the scale error. Source of uncertainties: 1) dE/dx formula, 2) the range calculation, and 3) knowledge of materials in the detector. We tentatively assigned +-3%.

• cos(Dth_Proton) distributions in each Enu_rec bin, norm by MRD 3D+1L.
• Simple spectrum reconstruction (to be uploaded soon)

• Q^2 distribution (2-track sample) and d\sigma/dq^2 (M_A).
  This shows the Q2 distribution for quasi-elastic dominant events. Solid curves represent the calculation of dsigma/dq2 with MA=1.0, 0.8 and 1.2 GeV/c^2. Errors shown are statistical only. Shaded area stand for the contribution of inelastic events which is estimated from the data (d-theta distribution).

• SFsummary: Table of SciFi number of events, event rate, and Nsk_expected (June99-July01)
  Updated on Dec.05 using new error of Nu spectrum(+6.49 -6.52). Nsk = 87.547 +10.62 -11.96 (Old error: +10.48 -11.82)
• Systematic Error Summary
• MRD3D event rate / 1L event rate as func of month.
  
• Reduction rate plots
  Normalized by MUMON: /Repro- /Goodspill- /Candiudates/
  Normalized by P.O.T.: /Repro- /Goodspill- /Candiudates/
  
• Basic distributions separated into 3D/1L, each year, overlayed with MC
