  Quadrupole scans were used to characterize the LEDA RFQ beam. Experimental
data were fit to computer simulation models for the rms beam size. The codes
were found to be inadequate in accurately reproducing details of the wire
scanner data. When this discrepancy is resolved, we plan to fit using all the
data in wire scanner profiles, not just the rms values, using a 3-D nonlinear
code.
