The nue analysis makes use of a sample of events selected by an electron-neutrino classifier. The expected spectrum in the Far Detector for any oscillation parameters is predicted on the basis of Near Detector observations.  The MC prediction for the background component is adjusted based  on  the  spectrum  found  by  the  same  selector  in  the  Near  Detector.   The  signal  prediction is adjusted based on the the observed numu spectrum in the Near Detector.  Cosmic ray background is estimated from the out-of-time region of the beam spills.  The observed spectrum of selected events in the Far Detector data is compared to this extrapolated prediction and we produce contours in sin^2 theta23 / dCP space, and use external constraints on theta13, dmsq32 and theta23 to favor/disfavor regions of dCP/hierarchy space.
