Summary of this reserach:
In the analysis of single transeverse-spin asymmetry in
PHENIX BBC, a hint for finite asymmetry is found in 
BBC-ZDC coincidence data. However, lack of information
in the present SpinLumi files prevents us from
performing further detailed analysis. So, we decided
to reproduce SpinLumi with  necessary ZDC information.
SpinLumi is directly produced from PRDF files.

Estimated CPU time:
Unknown (need to be tested)

Estimated disk space required:
Disk space for produced SpinLumi files -- 100 GB
Temporal space for PRDF files -- 1 TB (as much as possible)
  The total size of PRDF files is as large as 10 TB,
  which cannot be accomodated in disks. Realistic requirement
  is based on data amount which can be extracted from HPSS
  in 12 hours -- 1 TB.

Estimated space required in HPSS:
100 GB for produced SpinLumi files

Target date for completion: 03/31/03.

Plan for publication:
The result will be published as a PHENIX result, if possible.
