    Hi Rob,

    Is ours the best w measurement to date? If you haven't look at Tonry et
    al you might not have seen that we might be slightly better. If you
    don't want to look at Tonry et al, but can calculate the 95% confidence
    limits on w for our data after marginalizing over OM (after application
    of 2dFGRS and WMAP priors), then I could tell you whether we should
    highlight this in our paper. We could also compare that value to the
    WMAP+HST constraint on w from Spergel if you can give the 95% CL using
    w >= -1.

    If you do get a change to try to other 2dFGRS prior (from fitting the
    power spectrum), we might find very slightly better 95% CL's. These would
    be all the constraints I know of, so the result might actually stand as
    the best for a year or more (pretty good nowadays).

    Cheers,

    Greg
