Natalie,

Thanks for looking into this. Too bad it looks like my stuff does not
work. In fact, it looks like my corrections simply reduce statistics. The
before and after look about the same :(

I just realized that I have a full set of that are not skimmed. I'll try
and see if I can find out what is going on.

The part I find strange is that my momentum corrections can be quite
large, and noticeably shift the neutron and pi0 peaks, but your lambda
peaks, using my corrections, look not to have moved.

One thing you might want to keep in mind. When showing these sorts of
comparisons, you should keep the aspect ratio and size of plots the same.

Take good care,
Michael
