5 C D(SIGMA)/D(QMW**2)D(YW)D(OMEGA)
6 C for the specified jet types. This is trivial but done for
7 C compatibility with Drell-Yan and Higgs.

21 EQUIVALENCE (S,SHAT),(T,THAT),(U,UHAT)
23 C Angfac is (1-z**2), and is determined in terms of S,T,U.
24 C Note that both rho+- and rho0 are always elastic.
