    Hal, thanks a big bunch.  I will pick up a copy of "Astronomical
    Algorithms".  MICA was first on my list to get the source code.  looks like
    I am going to have to use my noodle a little for this project.  don't know
    how I missed the NOVAS library, but that looks promising too.  again, thanks
    a big bunch.
    these are the good old days
