Resumen

We provide three Fortran programs which evaluate the QCD analytic (holomorphic) couplings _Aν(^Q2) for complex or real squared momenta ^Q2. These couplings are holomorphic analogs of the powers a(^Q2)ν of the underlying perturbative QCD (pQCD) coupling a(^Q2)≡_αs(^Q2)/π, in three analytic QCD models (anQCD): Fractional Analytic Perturbation Theory (FAPT), Two-delta analytic QCD (2δanQCD), and Massive Perturbation Theory (MPT). The index ν can be noninteger. The provided programs do basically the same job as the Mathematica package anQCD.m published by us previously (Ayala and Cvetič, 2015), but are now written in Fortran.
