Hi, QA-ers

Just a heads-up that two things changed late yesterday in the database that 
could have impacts you may see in your QA examination of FastOffline data:

1) The TPC group modified some T0s

2) Vertex-finding parameters were modified.

Please keep in mind whether any differences you see in the data between 
yesterday and today may be due to something in the data itself, or simply in 
the reconstruction of that data as would be the case for database parameter 
changes. A consequence of reconstruction changes is often that for some runs, 
some of the files produced for that run are reconstructed before the 
modification and some after the modification, so runs taken close to the time 
of the modification show a mixture of before-and-after. Changes to the actual 
raw data are less likely to have a mixed period of runs, unless the change is 
somehow gradual over several hours.

Thanks,
-Gene
