JLab Farm Mini-Challenge Status
Mark presented the current status of the mini data challenge. See his wiki page for details. Nearly all of the 1000 data files have been generated and reconstructed, although there were failures in a few percent of them. He outlined the future work left to do. He will be starting another run soon.
Richard reported on event size and a study of how much of that size is Monte Carlo information that will not be present in the real raw data.
