Scribe: Colin Bischoff

Charge

The primary focus of this meeting will be technical and scientific progress towards the baseline design in general and the summer agency review in particular.

• Present results from or statuses of data challenge 6 with real delensing incorporated
• Foreground models / sims
  • Impact of foregrounds on delensing.
  • Foregrounds at low-ell
• Sketch path(s) forward for data challenges:
  • What questions need answering by the summer’s agency review that need results from data challenges?
• Outline trade studies that need to be done (or present results of trade studies) for the delensing LAT
  • Sensitivity vs resolution
  • Frequency allocation
• Outline trade studies that need to be done (or present results of trade studies) for SATs
  • Do we need 20GHz?
