Regrets: 

=== Agenda: ===

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

=== Notes: ===

  * 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(r) 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.
