Notes. The Tanh stepper f_step,Tanh is tested with different values (ω₋, ω₊, λ) as indicated in the first column. The subscript ()_new indicates no reset to previous density solution if convergence was not met. See text for details. Dashes mark models that did not converge at all. The last column gives the row total excluding not converged models. (Large numbers are abbreviated with K and M indicating 10³ and 10⁶, respectively).
