Attendance: Kris, Ragnhild, Mathieu, Shaul
Regrets:

1. Ragnhild
2. Mathieu MR Update
3. Kris

=== Notes (Shaul) ===

• Ragnhild thinks that C2 estimation of CMB spectra is ok. Proceeding forward.
• MR shows an update with results for model 96. Kris suggests to integrate the likelihoods to get proper limits.
  • Kris: you are doing r=0.003 and r = 0; but what if you have small r, but non-zero? Why are we using r =0.003?
  • Some discussion about the level of delensing. Why are we using 60%? SH to contact Julien Caron.
  • Kris: What are you assuming about the spectral index for synchrotron? We should not assume a uniform spectral index. What beta per pixel? notes are not clear about the answer
• Kris discusses his small scale synchrotron model: model is phenomenological, not physically motivated. It is tweaked to insert small scale 'mathematically', but not to violate what's know about the sky.
  • He takes Planck 353 GHz dust and modifies it. So the small scale synchrotron would be highly correlated with Planck's dust in small patches of the sky.
