AeGeo v2012 Programming Code

© 1992-2012 by James Q. Jacobs

The temporal variable for code values herein is epoch 2000.0. This code set is v2012.
More code may be found in the most recent Epoch Calc applet, an Excel file with a variable temporal setting.
Terms with var label are variable when date is altered. Values are UT1, except planetary periods are TT values.
