    Re: Angular Distance Between Stars
    From: Bill B

    Attached are zipped .xls and .xlsx spreadsheets for calculating angular
    distance. They can account for refraction and include temperature,
    pressure and elevation inputs; and employ many of the formulas the list
    has discussed.
    They were" ported" to Windows 7 OS/Excel 2010 from a Mac. They are also
    available in Mac OS 9.2.2/Microsoft Office 98 and Mac OS 10.4.11/Excel
    10.0.0 versions if you wish to contact me off list. I can port them to
    Mac OS 10.6 (Snow Leopard) /Excel 2011 if need be.
    The top three rows are not linked to anything and are there for
    record-keeping purposes only.
    The user has the option of entering GHA Aries and SHA's of the bodies,
    or GHA's of the bodies. If entering GHA Aries and SHA's, set the GHA
    cells to zero and vice versa.
    If I recall all of the cells that do not require user input are locked.
    The sheet is protected, but not password protected.  If you wish to
    change fonts, column widths etc. or just muck about, simply disable
    sheet protection.
    Any questions or bugs, let me know.
    Bill B
