    Hi Flemming
    
    I need a bit of decoding for this message from RHIC.
    
    I assume that it means:
    - that the 27 weeks scenario has been decided already.
    - that 5+14 of Au+Au means 14 weeks, in the best case of top energy running.
    -.that 5 weeks of development for polarized running means no experiment for
    us (?).
    
    Thus I would conclude from this that BRAHMS has to man 14 weeks + some
    detector setup time, say 16 weeks, amounting to about 336 shifts. Please
    correct my understanding as necessary.
    
    Could you indicate when you believe regular beam operations will start?
    
    BRAHMS collaborators (or group leaders) should then start submitting (to FV)
    concrete estimates of the shifts that they expect to be able to cover,
    together with indications of the preferred period to visit BNL.
    
    cheers
    JJ
