    Hi,

        Tony noticed that in my previous e-mail the days past discovery should
    read

    1) 9 days (~3.5 rest frame days)

    2) 13 days (~5 rest frame days).

        However, my conclusions are based on the correct scaling. Also, to be
    precise, the data are consistent with discovery at rest B max. Sorry for
    any confusion.
