  1. sensitivities (preliminary plots for your eyes only)

  2. Working hypothesies • SB+BB+Megaton Water Cherenkov at Fréjus • BB at g=100 • 5.8 1018 He or 2.2 101818Ne ions stored per year. • (double nominal. « relaxed duty cycle requirement to allow this » OK?) • 440 Ktons fid volume, 130 km, 20% photocathode coverage • SB from 3.5 GeV proton (SPLII) at 4MW • 10 years • band = (2%) 5% systematics on cross- sections * fiducial volume * efficiencies • Combination will be shown. • 2. Nufact with two baselines • (3000+7000 ~ e.g. Canaries 100kton +India 30 kton) Minos performance assumed. • 3.1020 muons of each sign in each direction / year. simultaneaous delivery of m+&m- • band = 2% (5)% systematics on matter effect. • 3. also shown is high gamma beta beam – • assumptions (intensities, detector) are not verified and this band will not be shown. • Only two plots will be shown. (not four)

  3. d=[90,180] d=[0, 90] d=[0, -90] d=[-90,-180]

  4. ibid with nominal beta beam fluxes.
