Legend: Bold face encodes 'need more information'; italics encodes issues that are (semi)settled in the sense that they are the basis for future discussions; Underlined Text are action items.

• Catch up on Action Items
  • Articulating interesting constraints on r: Raphael says there are specific interesting targets at a level of 10^-4. But we should shy away from constraining specific models. He will put together a group of people.
    • Amy: Are there specific landmarks that are worth reaching as a function of r?
    • Jamie: What is a useful \ell range? reionization sufficient? How important is it to probe the recombination peak? Shaul clarifies: the question is not one of delensing.
    • Al: is it important to have 5sigma rejection of high r or 2 sigma rejection of a lower r?
    • Amy: clarifying these issues will impact what goes into the science traceability matrix.
  • Delensing and resolution: Lloyd talked with K. Story. Planning to talk with Blake and Neelima. Will check their willingness and capabilities to do some analytical calculations.
  • Spectrometer: Al is starting to put a group together. He reports on some of the science targets they are considering. Jamie: can the spectrometer constrain inflation parameters with the spectrometer?
  • Bands: Shaul will present compilation of bands next week; we will then have to decide on nominal imager bands
  • Foregrounds Workshop: Graca is putting together a candidate program.
  • Involving the community in the Probe work: Shaul will compile a message.
• Should we investigate an EPIC-LC / LiteBIRD version? Yes. NASA costing of LiteBIRD may give a Probe-scale mission. Question: what is the process?
