Conditions for DC-1

Last Monday Mark sent out a list of proposals/decisions about details of the data challenge. We revisited some of these items.

Keeping track of particle parentage

Richard pointed out that a recent change that Paul pulled from the trunk into the dc-1.1 branch did not track parent particle ID correctly as intended, rather it only identified parent particle type. Paul needs this capabiltiy for his Cerenkov studies. Richard has suggested a change to the code to accomplish this and volunteered to implement it. He will do so and check it in on branches/sim-recon-dc-1.1. Mark promised to merge this change onto the trunk at the appropriate point in the future.

Events per file

Richard told us that 50 k events per job was about optimum for grid sites. We adopted that number for all of the sites.

Inclusion of out-of-time interactions
