Hello Matt, Nathan,
  I think it would be useful to have a sample of Moller candidate 
events easily available for studying all sorts of remaining systematics 
in our reconstruction.
 I've just committed a Filter Driver to skim Moller Candidate events:

org.hps.recon.filtering.MollerCandidateFilter.java

I start with the collection of Moller candidate vertices and then
impose additional cuts to clean up the sample.

I've tested it on a partition of run 5772 reconstructed with a recent
version of pass2, viz.

>  java -server -jar ~/.m2/repository/org/hps/hps-distribution/3.4.0-SNAPSHOT/hps-distribution-3.4.0-SNAPSHOT-bin.jar -r /org/hps/steering/production/MollerCandidateFilter.lcsim  -DoutputFile=tst -i hps_005772.evio.0.pass2_HPS-EngRun2015-Nominal-v3-fieldmap.slcio

With the following cuts:

<driver name="StripEvent"
                type="org.hps.recon.filtering.MollerCandidateFilter">
              <!-- Name of the Moller Candidate Collection of ReconstriuctedParticles -->
              <mollerCandidateCollectionName>TargetConstrainedMollerCandidates</mollerCandidateCollectionName>
              <!-- Maximum momentum of each electron, used to remove full energy electrons -->
              <mollerMomentumMax>0.85</mollerMomentumMax>
              <!-- Sum of the two electron momenta should equal the beam energy, this is the low cut -->
              <mollerMomentumSumMin>0.85</mollerMomentumSumMin>
              <!-- Sum of the two electron momenta should equal the beam energy, this is the high cut -->
              <mollerMomentumSumMax>1.3</mollerMomentumSumMax>
              <!-- Maximum difference in the ECal cluster times -->
              <clusterTimingCut>2.5</clusterTimingCut>
        </driver>

The output is quite manageable:

MollerCandidateFilter Summary:
events processed = 251823
events passed    = 3318
       rejection = 0.013175921182735494

Please let me know if you have any questions or need any additional information.
Any input on improving the cuts would be appreciated.
Thanks,
Norman

Hi All, 

It sounds like we are very close to pushing the button on pass-2.  Before we make the release, are there any last minute fixes?  I know that Sho is working on a bug in the GBL code and Omar is finalizing the dst-maker.  I need to fix the DQM code to work with the new track states.  Anything else?  I’d like to tell Jeremy to make the release next morning…yell if you working on something. 

Thanks, Matt
