    Dear Vitaliy,
    thanks for your interesting posting. Serena has been looking at
    the issues of intrinsic colors from nearby SNe, Jha's data
    included. I am sure she'll have something to add to your findings,
    in particular about dubious data points and parametrization
    functions.
    As for your comment on the impact on the
    precission of Knop et al results I think it what would be very
    useful is if Rob makes available the observed lightcurves that
    went into K03 in SNMINUIT format so that we can try out what
    the more recent color estimates and K-corrections yield, in particular in
    connection with even higher redshift data-sets.
    Cheers,
       Ariel
