data base situation

[David Zimmerman <zimm@physgi01f.phy.bnl.gov>]

Dear Gand Challengers.
Here is a description of the 
Organization of Event Data Bases on PDSF

There are:
3 full event data bases in existence.
/scrgc/data01/hij_FDID4003/             FDID=4003 <- This one has already 
					             been fully tagged
/scrgc/data01/hij_FDID4004/             FDID=4004
/scrgc/data02/hij_FDID2001/             FDID=4001
(note the mismatch on filename and fdid in last one)

Each contains 59 data base files (26 central collisions (big events) and 
33 Minimum bias (smaller events).  The central collision files contain
about 200 events.  The MinBi files contain 300 events.

Each directory also contains a setup.com file which loads the
objectivity module and sets the FDID.

The ddl's which were used to create these files can be found in 
/scrgc/data01/InfoHijing/
along with a file which describes the data contained in the data bases.
