[Halld-physics] Data Challenge Skims

[Paul Mattione]

I would like to get input from members of the physics and pid-upgrade groups on what kind of community-wide skims we want to have for the data challenge data.  At the physics meeting today I presented some off-the-top-of-my-head ideas for these skims, and how large they would be:

Some of these are obviously untenable (e.g. 2+ 1- is too large).  Others need to be tweaked (e.g. the cut on vertex-z may cut low-theta tracks that don't have enough resolution).  

I'm hoping this email starts a discussion on what data sets would be interesting to have.  Please let me know what you guys think.
