11 Sep 2012 BICEP2 weekly telecon
On the line:
Havard: John Kovac
Stanford: Walt, Jamie T.
JPL: Hien
Caltech: Randol, Jamie B., Pete, Jeff
San Diego: Jon Kaufman
Minnesota: Clem, Stefan, Chris
1) Weekly report from Pole [ Steff ]
- looks like another good CMB week, weather good to overcast
- load leveler fan / bldg temp disruptions during last schedule
Do we have a way to pinpoint this?
- cryo: drawing down Theo now, looking fine
2) Data quality / reduc czar report
Aug 18 - Sep 1 report [ Randol ]
Missing reducplots
Need fixes to code checking all reducplots made
Listed large # tags missing round 1 / round 2 cut
plots AI: Randol to fix code
AI: Look at why jobs are failing -- timing out
short_serial? Stationarity_ab cut removing large amount of data.
Some scansets with mediocre weather not being removed by
elnod cuts. 20120827C07 -- looks like v. large sky gradient,
bleeding into pair diff p1-3 modes. Not cut!
should it be? Does the p3 filtered data look OK?
20120830B01 -- snow on window? Correctly cut.
But passing most elnod cuts!
This week's report (email?) [Jon]
Recently generated tag browser
Mostly looks OK...
AI: Jon to study reducplots, present next week
next week's czar
status of B2 mass re-reduction [ Angiola/Randol ]
AIFL: stationarity_ab cut: Angiola/Jamie
AI: Walt to check in el nod gap cut
AIFL: elnod goodness-of-fit cut: Martin, status? -- remains open
outstanding B2 mass reduction actions?
3) Deployment/operations planning:
http://bicep.caltech.edu/~spuder/schedule/A-039_FY13_deployment.html
updated list emailed around
Steff would like to leave around Nov. 20
- November/December measurement plan [ Randol / Colin ]
- report on final B2 calibrations
most moon and BNS source data are not ideal for beam parameters
because of size of signal. need target ADU strength for ideal
beam shape meas.
- Zak to prepare FTS for Keck, also use for BICEP2
- October testing: thermal studies [ Jon ]
- To retro:
BICEP2 cryostat
other items? talk to John
items with JPL stickers that must go back to JPL
AI: Randol to look into these
4) Analysis updates:
- thermal analysis update? [ Jon ]
- UCSD proposes to look at cosmic birefringence w/ B1 and B2 data
Threads to initial B2 result:
- baseline data reduction
- are we satisfied with deglitching / other low-level
reduc? Believe so; Clem has asked for additional studies to verify
- are cuts doing a sensible job eliminating poorly modeled
data? Few outstanding action items; see reduc czar section
- deprojection
- baseline: relgain + diffpoint deproj (per phase or longer)
- using WMAP7 T derived templates
- Kendrick derived B spectrum estimators
2012 Sep 10: Rel-gain regression in the presence of template noise (for
BICEP1) (RWA)
2012 Sep 10: Deprojection sims 1211-1220 (CDS)
- systematic characterization
- statistics for reporting limits, r constraints
- foregrounds
- hope that BICEP1 3-yr results can provide us a model
to follow for these points
- other B2 analysis threads
