  KMC for investigations of the early instability stages: they are more easy to discern without the 
  
  discrete background noise of the KMC. Furthermore, one may perform a linear stability analysis of 
  
  the one-dimensional undisturbed streamwise front proﬁles with respect to transverse perturbations 
  
  (in analogy to the approach used in Refs. [19, 86, 87]).
