[Halld-physics] Talk Correction: Neutral KinFit

[Paul Mattione]

I just want to make a correction to what I showed in my analysis/omega talk yesterday: If you have neutrals in your final state, only do vertex-only kinematic fits.  Do not do p4 kinematic fits.  The errors in the neutral showers are too wonky and they throw off the distributions.  

I should have noticed this earlier, but thanks to Dave Mack for pointing it out (in my talk, see how the pi0 yield drops significantly when switching to the kinematic fit momentum (slides 20 & 21)).
