Comments:

The system is way overdriven. Need lower power. Maybe need to increase current diffusion. Should try smoothing over a few zones. SIngle lobe gives a more localized location of lh current drive. Try compound spectra or raising npar to 3. Interesting to see if the shear reversal location can be moved in this way. For more information about the run see the input namelist.
