Using the azimuthal order, m, and the inclination angle, i, determined from spectroscopy, the combination of two-color photometry and radial velocity data allows for simultaneous extraction of the spherical harmonic degrees, l, and intrinsic amplitudes, |?|, of pulsation modes. We present results for the identified modes observed in two well-studied ? Scuti stars: FG Vir and 44 Tau. The correlation between observed photometric amplitudes and intrinsic mode amplitudes is discussed.
