I appended two more plots for delta_LT, values shown are only the integral
results before multiplied with the kinematic factor C (=16alphaM^2/Q^6).

I am actually thinking to show only the deuteron gamma_0, not the other plots
but I am not sure what to show or what not to show. The best thing would
probably be gamma_0 and delta_LT extracted for the neutron to compare to
results in the paper I quoted before.
If anybody has any model, chPT calculations, or other world data on these
quantities, I would plot them together to compare and things would look more
meaningful.. I came accross a scaling expectation at large Q^2 that says:
delta_LT -> gamma_0 * 1/3 but, that already does not look good with our
models unless we expect a second oscillation before the values scale to a
constant at large Q^2...
Thanks for the inputs.
