The Dalitz plot parameters G, H, and K are used in the standard parameterization of the matrix element squared (see PDG): M**2 = 1 + G*X + H*X**2 + K*Y**2,where X = (s3-s0)/m(PI)**2 and Y = (s1-s2)/m(PI)**2, s1 = (pK - pPI0)**2, s2 = (pK - pPI0)**2, s3 = (pK - pPI+)**2, s0 = (s1+s2+s3)/3.

We have measured the transverse asymmetry from inclusive scattering of longitudinally polarized electrons from polarized 3He nuclei at quasi-elastic kinematics in Hall A at Jefferson Lab with high statistical and systematic precision. The neutron magnetic form factor was extracted based on Faddeev calculations with an experimental uncertainty of less than 2 %.
