Summary of low-ell BB work so far and sketch of plans forward (Oct 2019 UCSD meeting): [slides]

Active projects

  • Bayesian r-analysis: Millea, Knox, others
  • MAP phi estimate extension to curved-sky: Carron
  • Foreground clean map for phi reconstruction: Umiltà
  • Cross-spectra parametric r-pipeline: Buza, Racine, Bischoff, Pryke, Willmert
  • ILC pipeline: Flauger
  • SO pipeline: Errard

Inputs to pre-CD1 decisions

Pre-CD1 decision spreadsheet

  • Justification for 20 GHz channel on LAT: Bischoff
  • Justification for 85/95 and 145/155 split bands: Bischoff
  • Requirement for angular resolution and sensitivity of delensing LAT: Wu (slides)

Threads that can use more attention

  • Impacts of Galactic foregrounds on delensing
  • Instrumental systematics impacts on delensing
  • Instrumental systematics impacts on degree-scale measurements
  • Field selection for the deep survey
  • Forecast comparison between S4 and SO sims
  • Development of additional foreground models/sims, and development of an approach to managing our uncertainty about foreground properties and how this impacts flowdown to design.
  • Request from McMahon to Science Council for tool that can quickly calculate science forecast from noise specification, i.e. something like Victor's Fisher forecast.
