V.T164 — NGC 3198 Zero-Parameter Prediction

NGC 3198 (M_b=1.4e10 M_sun): V.T85 formula with Planck H_0=67.4 predicts v_inf=149.1 km/s vs observed ~150 km/s (0.6% accuracy, zero free parameters). V.D232 with local H_0=73.0 gives 122.5 km/s. V.T85 is the better velocity predictor; V.D232 is the better a_0 formula.
