Schedule: Report due on January 14.

Report Mechanics

• Re-release of engineering document scheduled for tomorrow. We're back on standard PICO repot.
• From now on, limited and coordinated editing, please. Talk with Shaul before editing.

Authorships/Endorsements - plan to release another version Friday, and a reminder after the beginning of the year.

• at 73 authors and 60 endorsers currently
• Add affiliations? Requested by JPL for release process. Past decision was no affiliations.
  • No objections from EC. Will proceed to add affiliations

Status of writing

• Updated version goal of this weekend. Monday 12/24 at latest.
• Executive Summary in progress
• Introduction will be replaced with 'Preliminaries'; 80% complete.
  • give general definitions like EE, BB, CBE, Baseline etc. Talks about comparisons to things like S3 and SO.
  • Idea is to give the reader the background they need.
  • JB: Is S4 comparison discussed? SH: No direct quantative comparisons. Some qualitative comparisons are mentioned. General ground complementarity is discussed.
  • AT: May consider introducing what the subsections of Chapt 2 are. Some guidance to readers.
    • SH: Good idea. Will work on this
  • AT: Science chapter starts with sentence on instrument. This is odd for the science section. Ideally document would flow science –> instrument to do that science.
    • SH: Makes sense. What about separating the 'Preliminaries' into its own section. And Science is chapter 3.
    • AT: I recommend 1 is EC that has highlights on science and instrument. 2 is science and focuses on that. Avoid saying “here's the instrument we designed, look at the science we can do.”
• Fundamental Physics
  • Inflation - 95% complete. F_nl requires work.
    • RF and SH will discuss. Figure unclear. Dash is without LSST below 20. RF has some doubts about figure. May need to talk with Marcel Schmittful.
    • Currently sentences about n_s and n_run. A factor of ~3 better than Planck (or Planck + SO). Should we keep things like this that are marginal improvements over known/funded? Or not mention those?
      • JB: Should only include things that are significant improvements. Too many modest improvements don't look like you need $1B when SO is $100M.
      • JD: But these small things add up. Maybe each of these factors of 2 are put together in one section. Like the parameter constraints beyond LCDM.
  • Other 95% complete - but DM improvements (including axions) relative to Simons are ~x2. Include?
  • Other - OK
• Extragalactic
  • 'First Luminous Source' - complete
  • Other (lensing, halo lensing, compton-Y) being rearranged - text tomorrow noon Central?
• Galactic - 100%
• Legacy - 98% complete.
  • Table 2.3 is a question enlarge or delete?
  • SO (and S4 source counts)
• Foregrounds - Needs review (SH) but Interesting Progress from Mathieu
  • Mathieu plot:
• Systematics - Done
• Requirements - Needs review (SH)
• Engineering - 98% done (SH to review)

Cover page

• Samples:

Parameter Constraints

• Beyond LCDM constraints from Eleonora di Valentino
• JD: Stronger model testing of LCDM.
• SH: Maybe we put all the factor of 2's like n_s, n_run.
• AvE: Important to distinguish between completed experiments (Planck) and planned experiments (SO or S4). Need to do much better than Planck, but marginally better than SO is more defensible.
