<h3>Summary of the Foreground session in Turin, February 9th, 2018</h3>
- Eiichiro overview:
running on idealized sims to match 10^-3. one pipeline matches
expectations (xForecast), the other still not optimized (Commander).
ACTIONS:
1) run on the configuration presented on the 8th.
2) extend multipole coverage by COMMANDER matching with e.g. NILC.
- Nicoletta on latest uptades on Synchrotron
synchrotron spectral index template outdated, need to work on new
datasets, S-PASS analyzed, revealing biases towards steepening of
average spectral index, substantial spread 5-10% across the southern
hemisphere.
ACTIONS:
1) run through component separation for checking differences with PySM
spectral index.
2) derive upper limit on synchrotron spectral index curvature.
- Ludo on dust modeling from latest Planck data
work in progress, checking how many dust components do contribute at the
r=1.e-3 level in the minimum; modeling based on Venxyngel model to be
improved.
- Mathieu
Runs not optimized yet, presenting COMMANDER results till l=50 only.
Benefit from low frequencies adding (C-BASS), not by extending the
high frequency coverage.
ACTIONS:
1) match with NILC high multipoles and derive constraints on r.
2) run on the configuration presented on the 8th.
- Josquin
Multi-patch analysis in progress, matching expectations, reaching 0.5e-3.
ACTIONS:
1) run on the configuration presented on the 8th.
2) Prepare package for wider use (with Poletti, Baccigalupi, Stompor, ...). |
