    I had put together an Excel spreadsheet to calculate separation (with the
    help of the list, Alex and his Meesus book). The second part of the
    spreadsheet introduces the affect of refraction to take it from
    no-atmosphere to what you should measure with a sextant.

    I would be happy to provide you with the spreadsheet off-list and some of
    the supporting documents/formulas in MSW if you wish.
