The Excel applet also
features Lookup menus to provide quick reference to numerical variables
and the AeGeo terms or codes. AeGeo is an astrogeodetic programming
code with intuitive, easy-to-learn astronomical shorthand. Input or
lookup any two combined code terms (Table 1) to find or utilize the
value, for example combine "l" (lunar orbit) and "r" (rotation) to
utilize the value of lunar orbit per rotation.
For ease of use, drop-downs
are labeled "menu" and input cells are labeled "input". An epoch
selector automatically adjusts the values of astronomical contants and
obliquity of the ecliptic. You can add new epoch variables or input any
year you choose. Altering the epoch selection will impact the numerical
drop-down menu if the selected value is subject to changing temporally.
A variety of epochs associated with ancient cultures are pre-programmed
in the epoch worksheet, where you can add others. The eclipse
calculator features are in the calc worksheet. The temporal selector is
in the v2009 worksheet, where correlated astronomical constant values
display along with lookup drop-down menus.
Some lookups support direct
input of code and display the value and the code term for easy
verification. All code terms are available in a single table in the
aegeo worksheet. The Excel name feature in the formula bar selects the
entire table to facilitate sorting. (I prefer not to create macros
because some users, for security reasons, do not download files with
macros.) The "aegeo" name selects the entire code table. Other named
ranges support the lookup and drop-down menu functions.
In the math calc area you
can input both codes and multiples. Adjacent unused cells in the
worksheets allow custom calculations. A variety of other features are
also provided, including a logarithm calculator, a Maya Long Count
converter, planetary data with a code lookup, and other conversion
tools. Formuls for all the constants are displayed in the formulas
Enjoy the applet. Feedback
appreciated. Expect updates in the future.
