The goal of high precision photometry is to reduce/remove correlated noise to achieve photon-noise limited photometry over all binning scales for all targets.  This website presents the IRAC team's best understanding of those sources of correlated noise and their mitigation including current techniques and recommendations for both planning observations and reducing data.  For more information on IRAC in general, see the IRAC website.

This website is relevant for you if you:

  • Need photon noise limited photometry for your science goals
  • Have, or want to plan for, staring mode observations
  • Observe time-variable signals at sub-percent precision level
  • Want to learn about the instrumental effects which limit high precision photometry

Do you want to be part of an ongoing discussion of some of the topics presented here?
