Notes by: Karl Young

Agenda

  • Schedule: 50 pg draft complete by next telecon; distribute to reviewers by Nov. 1
  • PICO Mission Website for additional report related documents
  • Quoting r constraints
  • Report
    • Inflation
      • Figures (Label lensing? show noise? remove data point labels, change prediction level to 5e-4? show Goncharov type models?)
      • Connection to lensing and Alex's part
      • Non-Gaussianity
    • SH Added 'Fundamental Fields' (PMF and birefringence) anyone wants to review?
    • Relics
    • Extragalactic
    • Galactic
    • Legacy
      • SH received new text from Gianfranco. Need to implement
    • Complementarity
    • Foregrounds
    • Systematics
      • Table?

Notes

Raphael's earlier forecast gave sigma® = 2e-5; we made it 2.5 times larger and used 1e-4 (2σ)

Stephen's Forecast:

  components: sync+dust
  delensing option: iterative delensing CMBxCMB 
  σ(τ=0.066)=1.95e-03
  σ(h=67.74)=8.41e-02
  σ(As=2.142e-09)=7.43e-12
  σ(r=0.0)=9.41e-05
  σ(Ωch2=0.1188)=2.11e-04
  σ(ns=0.9667)=1.08e-03
  σ(Ωbh2=0.0223)=1.86e-05
  effective level of foreground residuals, reff = 8.74e-07
  degradation of the noise after comp. sep. = 1.10e+00
  noise in the cleaned CMB map [uK-arcmin] = 9.02e-01

These forecasts were run using the CMB4cast Fisher matrix code (http://portal.nersc.gov/project/mp107/index.html, Errard & Feeney et al.), assuming access to T, E, B and d information, with the deflection estimated using the iterative EB estimator. The code assumes Planck-2015-level synchrotron and dust foregrounds, forecasting the experiment's ability to clean these foregrounds using a parametric maximum-likelihood approach, assuming the foreground spectral indices are constant on patches of size ~15 degrees across (N_side = 4). This is all probably a little out-of-date, being based on the Planck 2015 results and cosmology, but it doesn't seem to give a significantly different answer to Raphael's code (and I can rerun with a different tau if you'd like).
