* Duplicate of 2282 with different density profile *
* Duplicate of 2283 with n=n*2.0 *
* Duplicate of 2299 with changes to try and fix crash *

Comments:

This run is part of a density scan performed on 2283. It attempts, without success to fix a crash in 2299. A bad run, the qlim current is needed off axis which is a bad sign. Currents do not add, so the equilibrium solver was having trouble.
