The following plots are corrected data. The upper left
panel shows the orignial distribution, and the corrected. The upper right
is the correction between these curves on a scale that is easly to see.
The lower left is the correction that would be done if the correction was
only for the loss of particles.
The simdata went out to a Mt of 1.7 GeV, and the extension
of the data is an exponential fitted to bins 30-35.

The helions have efficiency corrections that are typically much smaller than the
errors. The simulation events used to produced these corrections, only went to 1GeV so the tail
correction seen in these plots is most likely an artifact. (the correction above about 0.6 should be
about 1). Also interesting to note is that the geant loss is almost 0 for all Mt.

The pion corrections go in the other direction for low mt. The
corrections are also larger.
