Telecon Notes Oct. 28, 2021

Attendance: Clem, Jacques, Mathieu, Julien, Sebastian, Shaul

Regrets:

• Delensing
• model 98 - nonparametric small section of sky
• Parametric update
• Paper
• Small scale synchrotron?

• Discussion of delensing:
  • Clem recommends proceeding with the maps he has already provided.
  • MR says the power spectrum extension to high \ell does not have non-Gaussianity.
  • Clem says only Van-Syngle had non-Gaussianity to high \ell
  • Clem can also provide maps from JD, model 98
  • Julien (grudgingly) agrees to proceed with what he has
• MR - Small patch cleaning
  • MR uses the B2 patch only. Estimate of r is not biased (consistent with zero), but sigma® is relatively large 7.5e-4.
  • Discussion about adding more sky patches: how? JD says he can work with MR to optimize a mask that will select several small clean patches of the sky.
• Clem asks: why not do model 99?
• Paper: discussion of figures proposals with MR. A request to analyze one more model MKD with r=0.003.
