Charge

General charge to all parallels:

We need to use the October collaboration meeting to advance our preparations for CD-1. Right away, we need to:

  • Identify key decisions that must be made (and justified) prior to CD-1,
  • Make progress on (or actually make) those decisions,
  • 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,
  • Ensure that those timelines and processes are understood and supported by the collaboration, and that we (together) believe we can follow them.

Specific charge to this delensing cross-cut session:

  • For the de-lensing LAT, what are the benefits and costs of variation in angular resolution (dish size) for legacy survey science goals?
  • What is minimum dish size / throughput needed for delensing? Would multiple smaller telescopes be better than one bigger one? (both r + Neff)
  • What are the effects of foregrounds on delensing (both for r and Neff)
