Telecon Notes June 24, 2021

Attendance: Charles, Mathieu, Kris, Shaul
Regrets:

1. Ragnhild - progress with Commander
2. Mathieu - models 93, 96
3. Kris - updates on small scale synchrotron

=== Notes (Shaul) ===

• Ragnhild is sick
• Mathieu shows results with models 93 and 96 (.pdf).
  • Slide 3 is a reminder what these models are
  • Slides 13,14 is r=0 for 93 and 96 (MR says there's an error with model 96?)
  • Slide16 gives the r=0 likelihoods
  • Slides 14 onwards give likelihoods with partial frequency bands
  • How are “sigma” quoted? Action: quote 95% upper limits by integrating likelihoods
  • Why are we using 60% delensing? Should use 73% (or 85%)
• Kris shows synchrotron at high resolution (.pdf)
  • maps at at 20 GHz; 2 deg resolution; taken from WMAP (LFI has 1/f noise)
  • pseudo spectra: information for l>80 is added by Kris
  • Action: communicate with Clem about having new maps
  • Next week: what is the prescription for adding small scale structure
