N-body RV fitting curves of nine close binaries with a_B < 30 au, including TOI-6963 Ab, HIP 90988 Ab, HD 72892 b, HIP 86221 Ab, HD 59686 Ab, HD 41004 Bb, HD 145934 Ab, HD 2638 Ab and HATS-37 Ab. We derived the dynamical minimum masses of these planets with the mass deviations ∣ΔM_p∣ = 4.1626, 5.7505, 28.2157, 0.1869, 4.4630, 88.5395, 15.2994, 0.2561, and 0.3961 M_⊕, respectively.
