    Ariel-- are you assuming "at max"? The slopes of the color curves are
    pretty steep. How does a z=1 at max compare to a z=0.7 five days after
    max? For the CFHT rolling search, we may be able to rule that
    possibility out-- however, it is something that should be taken into
    account.
