   It is given as a third input to `step!`. Value `true` is useful in (1) very fine grids, and (2)
   if some of the attractors are limit cycles. We have noticed that in this case the
   integrator timestep becomes commensurate with the limit cycle period, leading to
   incorrectly counting the limit cycle as more than one attractor.
+  `stop_at_Δt = true` should also be used if you want an accurate estimate of [`convergence_time`](@ref).
