Quadrupole scans were used to characterize the transverse beam of the LEDA RFQ. The original scan data, obtained when the HEBT was installed immediately downstream of the RFQ, were reanalyzed by fitting to the 3-D nonlinear simulation code IMPACT. All the data in the measured profiles at the wire scanner were used, not just the rms widths. The measured and simulated profiles still have differences in their shapes that have not been explained. An improved model is required to get better fits and may result in more accurate emittance measurements.
