Agenda:
Baseline configuration & data synthesis plans (Julian)
Work to date (Mathieu, Josquin as available)
Discussion on approach moving forward (All)
Attending: Shaul, Brandon, Lloyd, Charles, Kris, Jens, Jacques, Belen, Raphael, Mathieu, Julian
Notes (by Shaul tweaked by Julian):
Review of baseline configuration that can be used for simulations. Configuration posted on the wiki.
Charles argues that we need to optimize the focal plane, rather than assume a focal plane. Shaul and others argue that this a good goal but appears very ambitious for the time scales for PICO.
Julian describes what maps will be generated. Current pysm maps will be done by next week.
Path for MAD-based maps from Brandon/Chang-Goo:
Baseline will be a library of frequencies which PySM will interpolate between.
Validation work is ongoing. Raphael says E/B ratio is about 1.3, need to understand. Maps are only good for l=100, not higher.
Brandon: by next week could have several flavors of MHD-based foreground maps
PySM integration will take some time, and will come after other priorities. In the interim the library of frequencies could include the PICO basline band centers.
Charles argues we shouldn't ignore the low frequency; makes a comment that maps are only good for l<100.
l<100 is driven by resolution of MHD simulation. Brandon to follow up with Chang-Goo on running at higher resolution.
Raphael asks about interpolation between bands. Julian says we start by making delta function maps
Once we have the maps: who will analyze
Mathieu - Question: He has been running on PSM, will he migrate to pysm? Yes. Julian says currently not point sources. Mathieu says this will be needed later. All agree. Mathieu can run analysis at high \ell as well.
Raphael - He will run foregrounds removal. Raphael has some component separation algorithms as well. May use them.
Belen - Will apply SEVEM (used for Planck). Also working on neural network method. She wants the components to test whether the methods work.
Josquin - SMICA?
Julian to follow up with analysts on detailed map requirements (resolution, components, data splits, …)
Extragalactic skies will be coming from Marcelo Alvarez (based on peak-patch method from CITA group)
