keyword=Update VDC database: T0 update from Seamus
Bob asked me to publish new vdc database form Seamus for online replay.
To my understanding, it's come with new T0 offsets.
New databases are copied to timestamp sub folder of 20100330 as well as
newly added 20100326. Seamus produced two database *.T1 & *.T5 for
trigger 1/5 respectively. Currently, only *.T5 is used for both arm,
which seems to represent majority of the data. Some Mar 31 optics run are
replayed showing the new database carries better T0 offset.
There is a snapshot of the old database directory:./DB.backup.0402.
Old vdc database are renamed as db_L/R.vdc.dat.old
