PTF Survey Strategy

  • Period of year during which Survey runs: Main survey runs from March-November each year.
  • Filters: R band is used during bright time, and g band during dark time,
  • Cadence: Around half the time is a dynamic cadence (<1 day), and about half for a 3 day cadence. At least two exposures are taken of each field each night to eliminate moving objects.
  • Depth: The limiting magnitude is usually around 20-20.5 in R, although can be deeper in good conditions. Targets usually range from R=16-20.
  • Duration: The survey is funded up to end-2012.
