Tidal Parameters
================

The :nml_g:`tide` namelist group defines tidal parameters, as follows:

:nml_n:`y_T_thresh_abs` (default :nml_v:`0.`)
  Absolute threshold on dimensionless tidal potential :math:`y_{\rm T}` for a partial tide to contribute

:nml_n:`y_T_thresh_rel` (default :nml_v:`0.`)
  Relative threshold on dimensionless tidal potential :math:`y_{\rm T}` for a partial tide to contribute

:nml_n:`omega_c_thresh` (default :nml_v:`0.`)
  Threshold on dimensionless co-rotating frequency :math:`\omega_{\rm c}` for a
  partial tide to be treated as dynamic (rather than static)

:nml_n:`alpha_frq` (default :nml_v:`1.`)
  Scaling parameter :math:`\alphafrq` for tidal forcing frequency

:nml_n:`l_min` (default :nml_v:`2`)
  Minimum harmonic degree :math:`\ell` in spatial expansion of tidal potential

:nml_n:`l_max` (default :nml_v:`2`)
  Maximum harmonic degree :math:`\ell` in spatial expansion of tidal potential

:nml_n:`m_min` (default :nml_v:`-HUGE`)
  Minimum azimuthal order :math:`m` in spatial expansion of tidal potential

:nml_n:`m_max` (default :nml_v:`HUGE`)
  Maximum azimuthal order :math:`m` in spatial expansion of tidal potential

:nml_n:`k_min` (default :nml_v:`-10`)
  Minimum orbital harmonic :math:`k` in temporal expansion of tidal potential

:nml_n:`k_max` (default :nml_v:`10`)
  Maximum orbital harmonic :math:`k` in temporal expansion of tidal potential

:nml_n:`tag`
  Tag for controlling selection of other parameters
