Attendees: Alex, Sebastian, Gianfranco, Jean-Baptiste, Nick

Agenda:

- Imager v3 design updates (V3 located here under Frequency Bands and Noise: Specifications to Use)

Lensing forecasts

CMB lensing update

Cluster forecasts

With optical WL mass calibration with CV tau

clusters 140k Mnu 1-sigma : 10.8 meV w0 1-sigma : 2.29 % wa 1-sigma : 13 %

Any other forecast updates

Jean-Baptiste will post something soon regarding dust contamination.

Preparation for the May workshop: preliminary schedule

How to sharpen the extragalactic science case, in preparation for the report (what are the up coming milestones)

Additionally, we should consider what S3 or S4 + PICO joint analyses to highlight (possibly write papers)

Cadence for telecons

AOB

Minutes

-Very impressive lensing and cluster forecasts with the new v3 specs. -Need to include foreground cleaning for lensing, how does the lensing S/N degrade once we remove foregrounds. -Carry CMB lensing S/N through to parameters -For clusters consider lack of full-sky optical survey (LSST) -Consider correlated dust contamination, which Jean-Baptiste has started with v2, just needs to make plots and will ask Matthieu for v3 maps -Extragalactic sources, Matthieu maps are crashing the source extraction codes. Jean-Baptiste suggests running on a cluster and use small patches. Or we ask Matthieu to produce small patches. This is work carried out by Marco and Diego.
