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. \\
