1. Uncertainty in the spectrum shape from cross-section Pedro Ochoa December 8 th 2006

2.  Antineutrino cross-section shape has big uncertainty at low E: (plot by Donna Naples)  Knowing the uncertainty in the antineutrino spectrum shape is important for several analyses:  e ’s from  appearance, …etc

3.  As Hugh pointed out, one could try varying parameters that affect neutrinos and antineutrinos in the cross-section model.  Some examples: res qe res ratio all ma_qe scaled by ± 10% ma_res scaled by ± 10% ma_qe & ma_res simultaneously scaled by ± 10%
