Mathew,

With kaons there is always some level of misidentification that we have to
learn to deal with. It will be good to perform studies of kaon purity
versus different cuts on kinematic variables. Just saying "good particle
purity" is rather meaningless.

The article you post as evidence for your cuts is 18 pages and you give no
indication where the relevant information is! Are we all to read the
entire article?

It would be good for you to give a short summary regarding the relevant
information in the paper, or at the very least, give us some page numbers
where that information can be found. Asking everyone to sift through an 18
page NIM article is not very helpful.

Also, a NIM article on the TOF system can be a good place to start talking
about kinematic cuts, but that can not be the final word. It is precisely
this stage of the analysis where analysis cuts should be explored.

Take care,
Michael
