    For those of you asking about a figure that includes an example of the
    ridgeline fit-- the previous draft actually had one such. I removed it
    based on comments from Ariel that the figure was confusing and
    worrying. (Specifically, the ridgeline nature of the fit meant that the
    fit does not seem to go through the center of the distribution of the
    points, which raises questions about the color corrections.)

    The figure can be found at:

    Here is the caption as it appeared in that draft:

       Color curves from ``ridge-line'' fits to low-redshift supernova
       photometry from H96 and R99. Data from low-redshift supernovae are
       plotted, K-corrected and corrected for Milky Way extinction, but not
       corrected for host galaxy extinction. The line represents our
       ridge-line fit, which used asymmetric assumed intrinsic uncertainties
       and omitted systematically red supernovae.
