=== Agenda: ===

  * {{ ::20220113_commander_pico.pdf |Parametric update}}
  * {{ ::julien_20220113.pdf |Delensing}}
  * Paper

=== Notes: ===

  * {{ ::20220113_commander_pico.pdf |Ragnhild made progress on model 90.91}}. 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_20220113.pdf |Julien reports on the first results from delensing}}
    * 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?
