 The program performs an automatic global minimum search on the final fitted PES, harmonic vibrational analysis on the global minimum, in addition to provide ready-to-use subroutines containing the fitted n-body terms. These are output as CHIPR_DIAT_FUNC.f90, CHIPR_TRIAT_FUNC.f90 and CHIPR_TETRA_FUNC.f90 for two-body, three-body and four-body terms, respectively.
