+* `singular_min_accuracy = 1e-6`: A solution can be treated with a singular endgame method only if its [`accuracy`](@ref) is below this threshold. Otherwise, the solution will either be refined or labeled as unsuccessfully terminated.

   satisfied before a path is considered to diverge / go to infinity.
 * `val_finite_tol = 1e-3`: Tolerance on the valuation which has to be satisfied before the endgame is started.
 * `sing_cond = 1e14`: value for the condition number above which a solution is considered singular.
-* `sing_accuracy = 1e-12`: value for the accuracy number above which a solution is considered singular.

 * `scaling_threshold = -30.0`: Row scaling of matrices is only applied to rows with `e < scaling_threshold`, where is the norm of the row is estimated to be `2^e`. See [`skeel_row_scaling`](@skeel_row_scaling) for details.
 * `refine_steps = 3`: number of steps for refining solutions at the end.
