1. we aim to circulate draft in spin PWG ASAP
2. we will use only BTOW, TPC, perhaps ETOW for away ET veto. BSMD will not be used.
3. no reason to request another production for this publication
4. Z's (if confirmed) will not be included in this paper. BTW, the same holds if Zs are not confirmed.

List of task, TBD: assigned man power, status (clean it up , structure it )

1. STAR
   1. BTOW
      1. absolute calibration accuracy
      2. relative gains
      3. BTOW absolute gains + uncertainty
      4. Evaluate improvement in ET of 2x2/3x3 clustering vs. QCD-background rejection
         
   2. TPC
      1. identify reason for inefficiency at eta~0, no replay of BFC
      2. compare TPC track position accuracy data/MC
         
   3. Trigger

1. RHIC

1. 1. Vertex finder (PPV) vetting/debugging
      1. Jan: is 3cm accuracy enough for x-section paper?
      2. acceptance correction when triggered on L2W trigger
         
   2. Trigger
      1. relative spin dependent lumi (based on BHT3 in muDst)
2. assemble .tex files with outline of the paper
3. list of cross checks on the data
4. 1. 1. , QA
      2. absolute cross section from BHT3
5. theory calculation for our bins, vary input PDFs, average sign
6. 1. 1. spin bits or bXing --> spin pattern mapping
         
   2. VPD local polarimeter
      1. magnitude non longitudinal beam polarization
         
   3. Vernier scan (abs lumi @ STAR)
      1. determine BHT3 cross section
      2. estimate error, beam background contribution to BHT3 X-section
      3. vet BHT3 & BBC abs X-section used
         
   4. Simulations
      1. Vet MC/Data
         
   5. W-algo evaluation
      1. Background model for what's under the Jacobian peak

...

1. 1. 1. acceptance corrections (will need input from TPC track position accuracy)
         
2. RHIC Polarization
   1. pol patter per fill
   2. CNI Polarization

...

1. 1. , QA
      
2. Theory
   1. calculation for our bins
   2. vary input PDFs, average sign
   3. effect of non longitudinal beam polarization
