Erratum for Time Reversal in Neutrino Oscillations
  We suggested a new experiment for the MINOS project, with baseline L=735 km, to employ another detector at baseline 2L, which could measure TRV, as with a 10% e-mu conversion at distance L. There would be a 1% increase of the original flavor at 2L, which could be detected.
