Chris: J/Psi in dAu

Update in analysis was presented using BEMC information with own written cluster finder.
Discussion about E/p not beeing 1 even when using clusters. No SMD used. Final results using BEMC
are consistent with TPC only. Chris is preparing STAR note for paper.

BUR 11/12:

Rosi: to resolve Upsilon 1S from 2S/3S needs 100 pb-1 in pp. Amount of data to get precise measurement
      in AuAu depends on actuall supression scenario. If 1S not supressed we need about 10x more data than we have   

      now.

Daniel: Impossible beat PHENIX spectra of lowpt J/Psi in pp. However we have to consider J/Psi trigger to get
        the best of STAR. 
        For UU J/Psi flow would be interesting.We need MB data.  Usefull would be also high-pt trigger
        with 2.5-3.5 threshold. Suppresion factor will be estimated.
Chris: more dAu? again difficult to beat PHENiX.Perhaphs consider measurements over larger rapidity range.

Gang: for e-h correlations HT triggers similar to Run5 thresholds.
      UU electron v2 would be very interesting-> MB needed
      HFT in R12 can help with D and e-D.
