Telecon Notes Jan 13, 2022

Attendance: SH, Julien, Hans Kristian, Sebastian, Ragnhild

Regrets:

• Parametric update (.pdf)
• Delensing (.pdf)
• Paper

• Ragnhild made progress on model 90.91 (.pdf). This will be the only model in the paper. HK will need to finish the likelihood work.
  • Slide 10 'average' of Gaussian likelihoods
  • Slide 12 'average' of Blackwell-Rao r likelihoods
    • HK: Gaussian likelihoods are biased at low \ell, but perhaps good enough; Blackwell-Rao has a problem when the likelihood approaches zero. May need to bin at low \ell. Or use pixel-based likelihood?
  • Slides 15,16 - r estimates for 0.003 are biased. This needs more work.
  • HK has all the data to optimize Figures and he will fill in for Ragnhild

• Julien reports on the first results from delensing (.pdf)
  • Slide 2: forecast 0.78 defensing
  • He delenses over the full sky, fsky = 1 and gets 0.78 delensing. Same results with fsky = 0.44.
  • What are the next steps?
