    Dear Chellis,
    
    Thank you for your comments. Most have already found their way into the
    manuscript. The update on the kansas account will be
    forthcoming.
    
    I was intrigued by your mention of the growing width of the distributions
    with decreasing centrality.
    My primitive determination of the FWHM of the distributions
    (with a ruler on a fair sized plot, maximum determined around eta=1 i.e. at
    the 'peaks') shows, however, no trend that I
    would dare call systematic.
    0-5%       FWHM= 12.8 cm
    5-10%     FWHM= 13.0 cm
    10-20%   FWHM= 13.2 cm
    20-30%   FWHM= 13.2 cm
    30-40%   FWHM= 12.8 cm
    40-50%   FWHM= 12.8 cm
    
    In case, people get nervous about the cm scale, the conversion is 8.5 cm for
    5 units of eta. Thus the largest variation in FWHM
    is of order Deta=0.2.
    If anything, there is a slight 'bulging' at intermediate centralities -
    perhaps reminiscent of the bulging of our midriffs!
    Have I missed something?
    
    We think that rapid publication of a manuscript on 200 GeV from BRAHMS has
    higher priority than an extended reflexion period
    to the collaboration. In any case it has been good to see the rapid response
    with comments and opinions from a majority
    of BRAHMS groups.
    
    best regards
    and best wishes for Thanksgiving
    JJ
