    Obviously this is the only ethical thing to do.

    In fact, I think the rest of the astronomical community already believes
    that P99 underestimated the size of the uncertainty in the k-correction.
     When I was at Texas Alejandro Clocchiatti from the High-z team gave a
    talk titled something like, "The dark secret behind high redshift
    supernova cosmology." In the talk he said that you can move the
    cosomology around all over the place by changing your k-correction, and
    he was very open and fair about discussing the k-corrections they used
    and the uncertainties with them. Plus, I have had other conversations
    with people in the astronomical community that lead me to think that
    most people did not believe the P99 K-correction uncertainty.

    People would be much more shocked (and with good reason) if we tried to
    trot out the old k-corrections than if we updated them.
