    Here are the colors of the two knots, the "bridge" between the knot, and
    the nearby neighbor object. See the attached image for a visual
    definition. All magnitudes were measured from the GOODS release images.
    Apertures given are radii in pixels on those GOODS release images.
    Photometry is given in two apertures; 2.995 radius, and 4.165 radius.
    If you could do workups in both radii, we'd be grateful.

    Note that the actual supernova is in knot 2. The image is 2" across.
