text: FIG. 3: (Colour online) Dependence of the mean ﬁnger number left behind by the unstable dewetting 
  
  front on the particle-liquid interaction strength εnl. The regions marked (i) to (iv) are discussed in the 
  
  main text. The insets display typical snapshots obtained in the four different regions. Particles are black, 
  
  liquid is grey (green online) and the empty substrate is white. The remaining parameters are kT = 0.2, 
  
  M = 20, µ = −2.2, ρav 
  n = 0.1, (cid:15)nn = 2.0, domain size 1200 × 1200. For the insets, from left to right, 
  
  (cid:15)nl = 1.2, 1.4, 1.45, 1.8.
