    Hi folks,

    I discovered an error: in my conversion from f(lammbda) to f(nu) I left
    off a factor of lambda. So, all of the spectra should have a steeper slope
    to the red. This moves the knot2 colors younger by a few 100 Myr. This now
    makes the case even stronger for core-collapse, as the age is within the
    age range when CC SN actually explode. I have revised the plot (attached).

    If someone wants to check me on this, the data file
    /home/astro35/aldering/papers/99as/modeling/SB99_all/fig1d.dat contains
    the model spectra. They are labeled as having units of
    log(erg/s/Angstrom). I converted this to log(fnu)+C by adding
    2*log10(wavelength).
