ALGORITHM GUIDE FOR CREATING AN INDEPENDENT FUNCTION TO COMPUTE THE
NUTATION IN OBLIQUITY OF THE ECLIPTIC ACCORDING TO IAU SERIES 2000B
THERE ARE 77 TERMS IN THE SERIES
AUTHOR: Jay Tanner - 2011
A typical call to such a function might resemble:
dEpsDeg = Delta_Eps (JD)
The function would return the value of the nutation in obliquity
in decimal degrees for the time indicated by the JD argument.

EVALUATE THE SERIES FOR NUTATION IN LONGITUDE IN ARC SEC * 10000000
--------------------------------------------------------
Using the table data, the terms take the following form:
dEpsTerm = (DD + EE*T)*cos(arg) + FF*sin(arg)
Where:
arg = (m1*L + m2*Lp + m3*F + m4*D + m5*Om)
The angles are assumed to be in radians.
-----------------------------------------------------------------
Using the data table above, the following raw terms can be built.
Notice there are numerous elements that equate to zero. Those
elements may subsequently be removed and the remaining terms
algebraically simplified.
Each data line represents the elements of a term in the nutation series.
Compare the data table values to the numbers used in raw series below.
The variable s is used to hold the accumulating sum (s) of the terms
as they are sequentially evaluated. This value is converted into
decimal degrees at the end of the summation.

Algebraic reduction of the above yields the following simplified terms in a
format suitable for conversion into the BASIC programming language. Other
languages may also be able to use terms expressed in this format. Keep in
mind that the BASIC language is generally NOT case sensitive.

For conversion into Java, CPP or PHP the following term structures may
prove to be more convenient for translation.
All variables used in the terms are double-precision floating point.
In some languages, it may be necessary to replace sin(x) with Math.sin(x)
and cos(x) with Math.cos(x) instead.
