Hi all, BICEP2 team meeting today (Tues) at 9-10am Pacific. Thanks to each of you who sent reports AHEAD OF TIME this week, even late last night. Sorry these came too late for me to do the agenda yesterday, but please do look over the below before the meeting. Phone: 1-866-890-3820 (toll: 1-334-323-7229) Passcode:59702175 Walt will take notes <https://docs.google.com/a/cfa.harvard.edu/document/d/1iVrfX19cXQr8fUgRYOUosshApHAIteOzir9REQAN_y0/edit?hl=en_US&authkey=CL2j5rIL> for the team meeting. The bispud pipeline telecon will follow immediately, run by Clem. Except as called out below, all NEW analysis postings will be reviewed in the pipeline telecon, not the main telecon. 1) Weekly report from Pole [ Steff ] - yet another great observing week; good weather - Jon's thermal tests: 3 additional schedules run, report below. 2) Data quality / reduc czar report [ Walt ] AIFL: star pointing cut--fixed AIFL: El nod mismatch 20120929F10 <http://bicep.rc.fas.harvard.edu/bicep2/reducplots/201209/browser/20120929F10_dk068.html> follow up next week's czar: ________________ 3) Testing and Deployment Planning: Thermal testing report [ Jon ] 5-10 min Oct 9: xfer function low freq <http://bmode.caltech.edu/%7Espuder/analysis_logbook/analysis/20121009_therm_filt_v2> Oct 14: xfer function high freq (Jon, fix name!) <http://bmode.caltech.edu/%7Espuder/analysis_logbook/analysis/20121014_therm_filt> data great 0.0001-0.01 Hz, but 1e-3 response at 1 Hz? analysis/modeling needs work (offline!) - are we done taking xfer fun data? - PID characterization status November/DecemberMeasurement Plan <https://docs.google.com/a/cfa.harvard.edu/spreadsheet/ccc?key=0Ao4UxezLygx5dExiM2U4RHFyZmVFLU5wcmx0MlIwQkE#gid=1>(view only!) [ Colin (/Randol) ] 5 min - plan for pol rot? (need analysis of last year?) - plan for sidelobe maps? (who writes these schedules?) - plan for analysis? FTS status [ Zak ] 4) Analysis Status Reports: Baseline 2yr data reduction status report [ Walt ] 10-20 min Walt to give overview of this thread [ see his summary report appended below ] Characterizing non-beam systematics [ Walt / Angiola ] brief! briefly list threads / status / people: - relgain mismatch from per-channel abscal still in progress [ Walt ] - crosstalk, new posting to discuss next hour [ JET ] - other threads here: thermal, magnetic, ? Characterizing beam systematics [ Abby (/Randol) ] brief! briefly list threads / status / people: - main beam parameters [ follow up to Randol's post <http://bmode.caltech.edu/%7Espuder/analysis_logbook/analysis/20121004_beamstats/> last week ] - un-deprojected residuals (main beam and sidelobes) - other threads here: pol calibration errors, ? Deprojection / beamsim algorithm coding status report [ Clem ] brief! briefly list threads / status / people: - deproj sim test of linearity: add timestream noise [ Chris ] - deproj sim test of beam width/ellipticity [ Stefan ] - other: simulation of more complicated beam shapes, ? Data consistency check status report [ Chris (/Randol) ] big news: B2 2yr maps DK_jack cleans up dramatically <http://bicep0.caltech.edu/%7Espuder/analysis_logbook/analysis/20121008_sim1233/maps_pager.html> with deproj further discussion of new postings in next hour briefly list threads / status / people: - comparison of recovered deproj coefs w/ measured mismatches - full jack chi2's, sum_bp_devs, etc. Foregrounds status report: [ Jamie T ] brief! Statistics for reporting bandpowers, r constraints [ Colin / John ] brief! End. ---- Appendix, from Walt: Baseline two-year data reduction --------------------------------- What we've been doing: * Spent substantial time in 2012 addressing discrete artifacts in the data, including glitches and step-like crosstalk. * Cut definition is nearly complete. * The recent reducplots show the success of these efforts: there are only a very few examples of non-standard behavior remaining in the scan plots. Efforts now in progress and to be completed soon: * El-nod goodness of fit cut: - Now have strong evidence this cut is important for BICEP2: + 2012 Oct 12: Threshold-crossing gain change in GCP 165 (RWO) + 2012 Oct 12: Threshold-crossing gain excursion in more channels (RWO) - Martin has defined several new cut parameters - Angiola will regenerate cutparams files, cutplots, study thresholds - Regenerate cutparams, default cuts when ready. * Other cuts: - Thresholds for stationarity_ab and elnod_mean are now set. - Will take Jamie Tolan's adjustments to scanset_std and tfpu_std. - Angiola to make sure default cut thresholds get updated, include in new cut plots. * Follow-up on the few remaining oddities in reducplots. - Walt working on this now. - May require additional cuts or tweaks to existing cuts, thresholds, or deglitching. - In case of deglitching changes, could require new run of low-level reduction. * NTD calibration - Walt to propose scheme for applying offline cal for periods when needed. - Will redo low-level reduction for this period only. * Once this is done, can define stable TODs / data selection / cuts / pairmaps / reducplots. Next steps: * Write up final observing efficiency, etc. Easy -- follows SPIE papers with a few updates. * Human eyeball test for final version of all reducplots. - Will need volunteers... Decisions to make: * The high-weight catch has been removed from reduc_makepairmaps. Restore in reduc_coaddpairmaps or in reducplots? * How to make maps of dark TESs, dark SQUIDs, NTD? - How to apply cuts? - "clean" version would require substantial changes to code - put off until after BICEP2 first results? -- ___________________________________________________________________ John Kovac jmkovac(a)cfa.harvard.edu Assistant Professor, Astronomy and Physics, Harvard University 160 Concord Ave rm 310, Cambridge MA 02138, 617-496-0611
