[Halld-offline] sneak peak at data challenge files

[Justin Stevens]

Hi All,

Just a quick followup, the files Sean pointed to amount to 125M events with runnumber 9001 on the NU srm server.  I did a quick analysis of the pi+ pi- pi0 p final state with those files, copied over SRM, to compare with what we saw in DC1 (which Mark showed at the software review last fall).  The attached slides show the 3pi invariant mass before and after the kinematic fit cut.  There's lots of differences between the two datasets (reconstruction software, EM background, etc.) so I'm not trying to make a detailed comparison here, but just to say that a first stab at analysis of the DC2 data looks reasonable.
