====== Telecon Notes 20170705 ====== Attendance: Borrill, Hanany, Lawrence, Knox, Kogut, Crill \\ Notes by: Knox \\ ===== Action Items ===== * Workshops * Raphael/Shaul to finalize Foreground Workshop dates, location, program * Shaul to relay discussion of science workshop to Devlin/Jones. Converge on dates, location. * Simulations * Shaul to provide a set of frequencies from those currently available at LBNL; provide noise levels based on EPIC-IM (next week) * Lloyd, Julian provide more details for staging of challenge (two weeks) ====Hanany: galactic science working group update==== * Dave Chuss and Laura Fissel will co-lead this. \\ * Will solicit input from the community interested in galactic magnetic fields. \\ ====Update on 1st workshop (on foregrounds, possibly foregrounds + systematics)==== * Trouble with combining with KISS, so not doing that\\ * Dates: Looking at the last week of October (starting Oct 23), or potentially the following week for 2 to 3 days \\ * Location: San Diego\\ * Include systematics? JB argues against it. FG modeling is a huge constraint on all of the experiments. This is a community activity. Doesn't mix well with more specific instrument topic of systematics. \\ * BC thinks this may be too soon in the process to have a useful systematics workshop.\\ * CL emphasizes need to control systematics at the nK level, way beyond what's been done. Systematics very important and we should not put it off.\\ * BC and SH to be in touch to discuss systematics workshop, and whether it is added on to fg workshop, or separate\\ * If there are issues of space in San Diego, JB says LBL is an option. ====2nd workshop: time, location, announcement?==== Science and Complementarity Workshop\\ * When: SH says some time between March 2018 and June 2018\\ *AK says a major goal is to show NASA HQ and Decadal Committee that there is a lot of interest in this topic. \\ *AK suggests maybe a white paper would be good output from this workshop. SH says our report could be a white paper.\\ *CL says cost is just as important -- that there is a clear case that this is under $1B.\\ *SH says major goal for this workshop is to make sure Decadal is told how space and ground work together.\\ *CL: starting point is all-sky, lowish resolution complementarity with part-sky higher resolution, basics of that written down by a small number of people and then move forward from there. \\ *SH: We've switched to the idea of having this workshop *after* the space instrument is designed (just to clarify). So the workshop is to explore the complementarity after space mission is designed. \\ *SH: Danger of delaying: If Sept or Oct, we might not have enough time to digest developments between then and December when report is due.\\ *CL: Oct CDT report will have section on space/ground complementarity.\\ *SH: Input to that report won't have specifics on CMBP. So will be generalities.\\ *CL: We'll be able to go forward from there once we have CMBP specifics.\\ *SH: Will touch base with John Carlstrom and other S4 folks about some time in mid 2018 having this workshop.\\ *SH: CDT report section written by SH, Adrian Lee, and ...(missed it).\\ ====Full sky simulations==== *LK: Let's discuss what bands we're using.\\ *SH: has CMBP bands as starting at 30 and increasing by 1.2, all with width of dnu=0.25nu\\ *CL: we should include bands at lower frequencies than 30.\\ *JB: let's use what's already on disk, at least for first stage\\ *SH will select bands to be used based on existing bands; i.e., ones for which signal maps already exist.\\ *LK and JB to further develop the data challenge plan, with input from other interested parties, and how it is staged. \\
