• DFS justification
• GOODS goals (evolution of normal galaxies to z ?
  6, numbers, luminosity, size, clustering)
• DF simulations (mock catalogs) can serve to test
  algorithms for biases and quantify the impact of
  numerous observational effects
• They are indispensable tool in interpreting a
  wide range of observational data
• A suitable constructed mock catalog can also
  allow us to connect the observations directly to
  modern models of structure formation
