-    Were it not for the eccentricity of Earths orbit, this would be a trivial function.
-
-    We compute the Earths orbital position with respect to perihelion, from which we derive a
-    'velocity correction factor'. We then compute the orbital angle with respect to the
-    December solstice, as 'modulated' by that correction factor.
-
-    Due to the accumulation of rounding errors, the computed December solstice of 2135 will lag
-    the actual solstice by many hours. A fudge factor, 'LAG', distributes the error across
-    the 136 year range of this library.
