306353950
'bad chunk' (known previously) - awaiting GR update
313483912
missing 700s, being worked on

- 1/12/2011 - Expand P120 coverage to include Crab ToO
- Crab ToO 9/23/2010 15:50:50 to 9/27/2010 19:49:38, corresponding to MET r0306949696-r0307308940
- reconfig through end of Sep 2010: 10916 -> 11841 runs, increase of 925 runs
- No recon file for run 306353950 (being worked on, for the moment, place dummy file in runFile.txt)
- First run in new block completed, awaiting checkered flag to continue...
- 8/29/2010 - Discovered three merge steps that silently failed (xroot file access). TASK complete.
- 8/28/2010 - processing formally complete (10916 runs), but some discrepancy in # of events
- 8/26/2010 - serious xroot problems. See initial distribution of files across xroot servers. From this report (courtesy Wilko) it is easy to see where problems are likely to arise - when the number of servers involved is small, e.g. two or three.
- 8/19/2010 - production continues at a crawl due to xroot server difficulties
- 8/16/2010 - resume full production, but at a slow trickle (max 350 simultaneous processClump jobs)
- 8/8/2010 - block 2 reprocessing complete. Many xroot server problems. (5 days to process 2084 runs)
- 8/3/2010 - begin block 2 reprocessing (through 255132033 MET), bringing the total runs reprocessed to 2721, about 5-1/2 months of data.
- 7/28/2010 - block 1 re-reprocessing complete
- 7/27/2010 - New GlastRelease (v17r35p10) containing new evtUtils, "to make the FT1EventClass bits compatible with the ScienceTools". Cleanup, including removing all files created last week during the first attempt.
- 7/21/2010 - block 1 reprocessing complete
- 7/20/2010 - agree upon 'pilot block' of runs (239557417 - 243220241), 637 runs. Begin...
- 7/19/2010 - submit first test run. success. await feedback
