Attendance: Shaul, Jacques, Julien, Sebastian, Kris, Charles

Regrets:

• Delensing
• Paper
• Tech gap
• Commander update
• NILC - smaller sky area

* Julien + Sebastian: Clem produced maps but foreground information drops at \ell=1500. For S4 power does not drop for some models. **Shaul will check with Clem**. 
  * JD: PySM is an nside=512 which gives \ell = 1500. They are working on increasing nside but it isn't ready yet. PSM maps have information going to \ell=5000. 
  * SH: do we need information at high \ell? JD shows spectra of dust maps between 40-220 GHz that show power to high \ell
  * Julien: S4 needed only minimal separation using the central frequency bands. This is not an issue for a small clean patch, but may be an issue for 50% of the sky
  * Kris: what about point sources? 
  * JD: for CORE we have done cleaning at nside=2048. 

• SH show proposal for paper figures. See below. Need to communicate with MR.
• Paper: Proposal for NILC Figures
  • Start with r=0.003
    • one (90.91) showing 10 sims including cyan, green red.
    • One (90.91) with the average
    • one (90.91) with likelihood
    • (all the rest in an appendix)
    • 90.98 with average
    • 90.98 likelihood
  • r=0
    • same as above

• Charles gives outline for gap list paper.
