    I have an old Apple PowerBook G4 and may not be able to use Excel but others will surely find the spread sheet useful if you can find it.

    Many years ago I developed an Excel.xls spreadsheet for precisely
    determining distance between stars including some formulas provided by
    Alex and his library. Instead of using "backwards" refraction it
    calculates it directly, and has inputs for temperature and pressure as well.

    If you are interested I'll dig around in my archives and post it.
