by Bert Pool, is not entirely clear to me. There is a numer 2 in the
numerator of the radicand that I can not place with 100% certianty; this is
because the formula has always arrived in a slightly jumbled form, and I
have to reconstruct it.

should be (2*pi^2) (well at least that is what my file says)...
the radicand/formula should read:
/--------------------------\
/ 2*pi^2*(d1-d2)*(d2/2)
C = (1 + (0.2781 - (d2/d1) ) * (2.8) * / -----------------------
\/ 4*pi
(hoped it turned out...)
