text: this regime. In this parameter range, demixing of particles and liquid occurs at the moving front 
  
  and increases its transverse instability. In this ‘demixing regime’, the wavelength of the ﬁngering 
  
  instability is determined by the dynamics and the energetics of the system. Decreasing εnl further 
  
  (below 1.4 in Fig. 3) one ﬁrst observes in regime (iii) a slight decrease in the average ﬁnger num- 
  
  ber. This is a geometric effect resulting from our one-dimensional ﬁnger counting routine: The 
  
  ﬁngers increasingly break up and the dried-in pattern looks progressively isotropic. In regime (iv), 
  
  the measure (cid:104)f (cid:105) does not represent a ﬁnger number but instead indicates a decrease in the typical
