     88Since FastJet version 3.1.0, the pile-up density can be computed using a fixed grid, resulting in much faster calculation.
     89This can be done by calling the module !FastJetGridMedianEstimator. You can specify different regions as before, and, in addition,
     90the grid-spacing in eta, phi:
     91
     92
     93{{{
     94module FastJetGridMedianEstimator Rho {
     95 
     96  set InputArray Calorimeter/towers
     97  set RhoOutputArray rho
     98
     99  # etamin etamax gridsize_eta gridsize_phi
     100 
     101  add GridRange 0.0 2.5 0.5 0.5
     102  add GridRange 2.5 5.0 0.5 0.5
     103}}}
     104
     105Both the ATLAS and CMS pile-up card are released equiped with !FastJetGridMedianEstimator since Delphes 3.2.0.
