TSF - Under-relaxation parameter for current update iteration.
PHI2 - Iteration parameter used to optimize over-relaxation of inner iteration.
SF - Iteration parameter used to optimize over-relaxation of inner iteration.
Lowering SF can help the convergence of difficult equilibria.
NSPEC - Number of particle species present (for IBOOT = 3 bootstrap option).
SCALEP - Used with the TSC profiles. SCALEP > 0.0.
DBWRT - Switch for writing scalar and profile database files.
0.0 
Don't write dbequs, dbequp
1.0 Write dbequs and dbequp
If DBWRT> 0, the first 8 letters of the top line in the inequ input file are
used as an identifier for the equilibrium calculation.
