We provide a successful fit for proton-neutron scattering below pion
production threshold up to LAB energies of 350 MeV. We use seven high-quality
fits based on potentials with different forms as a measure of the systematic
uncertainty. We represent the interaction as a sum of delta-shells in
configuration space below the 3fm and a charge dependent one pion exchange
potential above 3fm together with magnetic and vacuum polarization effects.
Special attention is paid to estimate the errors of the phenomenological
interaction.
