  FDCHQHP is a Fortran package to calculate the transverse momentum (p_t)
distribution of yield and polarization for heavy quarkonium hadroproduction at
next-to-leading-order (NLO) based on non-relativistic QCD(NRQCD) framework. It
contains the complete color-singlet and color-octet intermediate states in
present theoretical level, and is available to calculate different polarization
parameters in different frames. As the LHC running now and in the future, it
supplies a very useful tool to obtain theoretical prediction on the heavy
quarkonium hadroproduction.
