• Precession Period (Kris, Jacques)
  • 10 hour precession period:
  • 48 hour precession period:
  • More Slides
• Noise/Bands Figure
• Noise Requirements vs Best Case Estimate (BCE)
  • Proposal: Req = BCE*rt(2)/0.9, independent of frequency
  • rt(2) because “Planck achieved noise within ~20% of BCE” (to be checked)
  • 0.9 because the cost models assume 90% yield
  • first factor is applied on individual detectors, second factor on the array.

• Precession Period (Kris)
  • Shaul: we've debating whether fast or slow precession; Jacques's argument was too fast precessions give large gaps
  • high-resolution, 1.6 arcmin simulations
  • 10 hours vs 48 hours
  • first slide
    • blue (or gray on right side) is either 0 or just a few hits
