Comment on "Search for Muon Neutrino Oscillations with the   Irvine-Michigan-Brookhaven Detector"
  The neutrino flux used in Becker-Szendy {\em et al.}\cite{BZ} is now known to be   in error. Becker-Szendy {\em et al.}\cite{BZ} depended heavily on the   Lee and Koh flux\cite{LeeKoh} which was noted as erroneous in Gaisser {\em et al.}\cite{Bug}.   This makes the results of Becker-Szendy {\em et al.}\cite{BZ} unreliable.
