With recent advances in the precision of inclusive lepton-nuclear scattering experiments, it has become apparent that comparable improvements are needed in the accuracy of the theoretical analysis tools. In particular, when extracting parton distribution functions in the large-x region, it is crucial to correct the data for e ects associated with the non-zero mass of the target. We present here an updated, more accurate, version of our calculations based on the Jacobi polynomial expansion method on performing a global t to the existing data by imposing target mass correction e ects. The e ects of these corrections are studied and polarized structure functions with and without them are compared.
