Comments:
This run is a duplicate of 2305 but with n=n*58. This puts the central density
down to about 3.e20. LH current increases, but a large amount of ohmic is still driven on axis lowering q(0) to one.
The lower density decreases the bootstrap current. Overall not a very interesting case, average fbs=23% and max fbs=29%
For more information about the run see the input namelist.
