 * \brief NRSur3dq8Remnant model for remnant BH mass, spin and recoil kick for
 * aligned-spin BBH.
 *
 * The binary data file is available at:
 * https://dcc.ligo.org/LIGO-T1900034/public.
 * Get the lalsuite-extra repo or put the data into a location in your
 * LAL_DATA_PATH.

 * **Paper**: https://arxiv.org/abs/1809.09125,
 *    https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.122.011101.
 *    The model is referred to as surfinBH3dq8 in the paper.
 *
 * **Parameter ranges**:
 *
 *   q = [1, 9.1]
 *   \f$\chi_{1z}, \chi_{2z}\f$ = [-0.91, 0.91]
 *
 *   OR
 *
 *   q = [1, 10.1]
 *   \f$\chi_{1z}, \chi_{2z}\f$ = [-0.81, 0.81]
 *
 * **Training parameter ranges**:
 *
 *   q = [1, 8]
 *   \f$\chi_{1z}, \chi_{2z}\f$ = [-0.81, 0.81]
 *
 *   But extrapolates reasonably to the above mass ratios and spins. However,
 *   if a guarantee of accuracy is required, this model should be used within
 *   the training parameter range.
