Science and Data Simulations

• DS2T1 Science Simulations
• Goal provide realistic sky models to be used
  for input in telescope simulators
• DS2T2 Data Simulations
• Goal provide software tools for simulating SKA
  observations using the T1 sky models

Science and Data Simulations

• Overall assesment
• Science simulations are a great success and are
  also being used outside the SKA(DS) community
• Data simulations prove harder than envisaged.
  Gave great push to the MeqTree package providing
  a very flexible infrastructure for adding
  functionality. Still work to be done but will
  flow into Path2SKA
