• AAS2019 (Shaul)
• TeamX slides (Amy)
• Noise/Bands Figure
• Noise Requirements vs Current Best Estimate (CBE)
  • Proposal: Req = CBE*rt(2)/0.9, independent of frequency
  • rt(2) because “Planck achieved noise within ~20% of CBE” (to be checked)
  • 0.9 because the cost models assume 90% yield
  • first factor is applied on individual detectors, second factor on the array.

AAS2019 (Shaul)

• End of May is special session request deadline. No current Probe special session planned for 2019.
• SH: contacted Asantha Cooray and Jason Glenn suggesting a group special session. These 3 are most related probes. Would give 1/2 hour to discuss each project. Timely since right after reports finished.
  • HH: yes. Good idea. Gets outcome of probe studies out broadly.
  • AT: surprising if NASA doesn't do this for all Probes, but this can be replaced if NASA makes full probe session.
    • SH: separate sessions give more time per study. That would better.
    • AT: Agree, just expect NASA to set one up. But if multiple sessions already set then NASA maybe doesn't bother.
  • SH: Will proceed with this 3 group session plan. Plan of 3 thirty minute talks. 30 min per probe. groups can subdivide. 2 weeks to submit this. Iterating with Asantha and Jason.

TeamX slides (Amy)

• No specific hang-ups. Feelers out to export office on process.
• Process will probably be weeks to release.
• SH: I can flag a subset that is most important to release.
  • AT: ok. that would shorten time to release.

Noise/Bands Figure

Noise Requirements vs Best Case Estimate (BCE) Current Best Estimate (CBE)

• AT: standard NASA term is current best estimate (CBE)
• starting from r is awkward as foreground limits aren't well understood. so r values don't set a noise requirement.
• we'll adopt this empirical noise requirement and iterate that with science case.
