 Here ``NPARAM`` is used to specify the number of parameters used to define the PES. ``POT_TYPE`` is the name of the potential energy surface being used which is defined in the ``pot_*.f90 file``. The keywords ``COEFF`` indicates if the potential contains a list of parameter values (``LIST``) or  values with the corresponding expansion powers (``POWERS``), e.g. (for H\ :sub:`2`\ CO):
