Charge

  1. Identify key decisions that must be made (and justified) prior to CD-1,
  2. Make progress on (or actually make) those decisions,
  3. Lay out a timeline and process for making each decision, consistent with the post-decision work and internal reviews that will be needed to complete preparations for CD-1,
  4. Ensure that those timelines and processes are understood and supported by the collaboration, and that we (together) believe we can follow them.

Key Issues

  • How do we optimize detector allocation across frequency in the face of uncertainty about foreground properties, for both the SATs and the delensing LAT?
  • What are the advantages of split bands? How does performance compare to non-split bands?
  • Do we need a 20 GHz channel on delensing LAT (for SAT science)
  • How well will de-lensing work in practice?
  • What are the necessary analysis tools to answer these questions?

Agenda

  1. Introduction by everyone in the room: who? where? what aspects of low-ell BB interest you? 5 minutes
  2. Recap of the plan for this session/CD-1 goals [Wu], 3 minutes
  3. Review of Fisher based S4 forecasting thus far leading to DSR appendix A [Ben], 15 minutes
  4. Review of Map based S4 forecasting thus far and ideas for next steps Clem, 10 minutes
  5. Review of forecasting and simulations for Simons Observatory inflation science [Alonso / Errard / Sherwin], 30 minutes
  6. Plans for working group [all], ~60 minutes
    1. Forecasting
      • Quantitative comparison of SO and CMB-S4 DSR forecasts
      • Feedback loop between forecasting and data challenges
    2. Data Challenge simulations
      • More / better foreground models
      • Instrumental systematics
      • Other map non-idealities, i.e. filtering / mode loss
      • Coordination with technical groups on instrument configuration, etc
      • What else needs to be demonstrated for CD1?
    3. Analysis of Data Challenges
      • Who plans to participate? How do we get more participation?
      • Delensing
