Detailed Description

Kachaev's version of the AMP parameterization.

From the original fortran code: Source: K.L.Au et al, Phys.Rev. D35, P 1633. M solution. 04-Mar-2003 See eps_k1.for for description. Here matrix M=K^{-1} is parametrized with one pole. Misprint in the article (other than in K1–K3 solutions) was corrected.

14-Mar-2003 Nice amplitude for pi-pi S-wave without f0(975). It is smooth and nicely tends to zero after approx 1.5 GeV. f0(975) pole excluded; coupling to KK zeroed; set C411=C422=0. The largest effect from C411, zeroing of C422 looks insignificant.
