The joining factors in the above formulas are given by
where Anm(h2), Bnm(h2) are as in §28.4(i), and
Cm(h2), Sm(h2) are as in §28.5(i). Furthermore,
Here meν(0,h2) (≠0) is given by (28.14.1) with
z=0, and Mν(1)(0,h) is given by (28.24.1) with
j=1, z=0, and n chosen so that
|c2nν(h2)|=max(|c2ℓν(h2)|), where the maximum is
taken over all integers ℓ.
