    Not today. That's a little more involved than anything I can do
    immediately.

    There's also the issue of the right spectrum to use for color correcting
    the star... and since all my code uses SNe template spectra, plugging
    that in isn't trivial. (It's certainly tractable, but I'd need a bit
    more time and lack-of-franticness to really get it done.)
