FACIMP - Error tolerance for inner loop elliptic equation solver. If FACIMP is negative, will be used as the error tolerance, and will be divided by 5 at each grid doubling. This can be useful in removing glitches in near the axis caused by an insufficient number of iterations following grid size doubling.
NIMAX - Maximum number of inner iterations before metric update.
ITOOFF - Number of iterations which use fit at origin.
JORGN - surface number at which fit is made for iterations < ITOOFF.
TSAW - Sawtooth parameter for temperature profile.
() = TSAW T() + (1-TSAW) T().
ESAW - Sawtooth parameter for Taylor state current profile.
= ESAW + (1-ESAW) ().
RSAW - Relaxation parameter for sawtooth model.
