This is actually quite interesting. The LH is turned off at 0.5s, so the LHCD just goes away. The Ohmic almost automatically replaces
the lost current. Ohmic then increases and penetrates in and the bootstrap decreases. LHCD seems crucial for making RS and keeping
the bootstrap current high. Re-run with higher resolution and no LH smoothing.
For more information about the run see the input namelist.
