Ion Parameters in Amber99bsc1 Force Field

Hello,
It is unclear to me which set of ion parameters is used in the BSC1 force field. I want to use the Smith-Dang ion parameters (Smith, D. E. & Dang, L. X. J. Chem. Phys. 100, 3757–3766 (1994).
) in GROMACS? Any help is highly appreciated.
Thank you in advance for your assistance!

Best regards,
Fatemeh
