Dear Edward. Would it be possible to implement the calculation of the parameter: w_e ? The Omega_eff (Effective field in the rotating frame) ? http://www.nmr-relax.com/manual/Dispersion_model_summary.html
As seen in the model DPL94 for 2-site off-resonance fast exchange relaxation. http://wiki.nmr-relax.com/DPL94 This would come in handsome for producing .out files with w_e and for the wished plotting feature.
