[Hps-analysis] 4-Hit Tracking Update

[Nelson, Timothy Knight]

Hi Bradley,

I don’t think that’s relevant.  It looks like the rate at which more tracks are found with only 4-hits required is pretty constant above about 200 MeV: the distribution doesn’t seem to have changed.  Of course, the distribution is peaked around 300 MeV, so the increase translates to the largest absolute change there.

If you want to see better what is going on, use wider binning to reduce statistical fluctuations (try 20 MeV bins) and divide the 4-hit distribution by the 5-hit distribution with proper binomial errors.

Cheers,
Tim

What's interesting is that extra V0's are now found, mostly low-momentum (~0.3 GeV):
