Comments:

This run is supposed to show shear reversal control by changing the npar spectrum. The LHCD seems to penetrate a little more before damping near the bootstrap current peak than the npar=3 case. The LH power is about right. Might try turning down the current diffusion a little and making the re-run switches. For more information about the run see the input namelist.
