| - | Jamie credited with writing notes back in June\\ | + | Raphael hasn't called |
| - | Action items from last week:\\ | + | Clem brought up the subject of a joint workshop with S4, response was not overwhelming\\ |
| - | - contact Kovac about a probe talk at Harvard S4 workshop (Shaul called)\\ | + | This was in reaction to an approximately equal split in time over a 3-day period\\ |
| - | - communicate with John Carlstrom to share resources with S4 (reply pending)\\ | + | Perhaps one could have the probe go first\\ |
| - | Primary work on spectrometer has been on foregrounds\\ | + | Has there been any discussion about using S4 tools for the probe?\\ |
| - | Spectrometer has shallow sensitivity up to several THz\\ | + | There certainly seems like there is overlap in certain areas, e.g. foregrounds, analysis machinery\\ |
| - | May offer some useful information for deep imager data over narrower range of frequencies\\ | + | S4 people did think a coordinated approach |
| - | What is the utility of high-frequency | + | No reply yet on the request to have a presentation at the Harvard meeting\\ |
| - | The spectrometer will provide good information on dust opacity | + | |
| - | It is less clear if this knowledge will prove useful at nK sensitivities\\ | + | No suggestions about probe naming plan put forward\\ |
| - | Can the effect of decorrelation | + | |
| - | Shaul: | + | Update from the data challenge (Julian)\\ |
| - | Charles: we can't assume we will know the spectral properties of the dust\\ | + | Mission observation applies to a sky model in selected beams and band passes\\ |
| - | Question is does the spectrometer provide essential information for foreground removal?\\ | + | The initial sky model is PISM2\\ |
| - | Jamie: | + | Output maps will be available tomorrow |
| - | Jamie: | + | Described as a " |
| - | Al: Probably not, but I can quantify especially in combination | + | Teams of analysts were solicited by Lloyd, we should find out who has signed up. Lots in Europe presumably\\ |
| - | Can we get a picture of MIDEX/PIXIE to get some idea of physical size?\\ | + | Clem: |
| + | Yes, though there are differences and limitations from what these groups have done\\ | ||
| + | For example CORE++ has moved beyond PISM, machinery already exists\\ | ||
| + | |||
| + | Update from the Technology WG:\\ | ||
| + | Jeff and Roger have been working on a detector technology plan for team-X\\ | ||
| + | Getting some input from LTD, baselining TES+TDM SQUIDS for the probe\\ | ||
| + | Then we would outline what the CMB community has done, and diverse future improvements\\ | ||
| + | Optical coupling can be left open, highlighting diversity | ||
| + | Plan to circulate | ||
| + | Jamie: | ||
| + | We should be concerned that the probe study is for a mission | ||
| + | Therefore it could fall out of long-term technology funding, and we should anticipate writing a technology white paper to justify continued investment\\ | ||
| + | High-frequency channels | ||
| + | The other questions from Shaul can be addressed in the Imager telecon\\ | ||
| - | Systematics working group has been collected, reviewing existing tools and knowledge.\\ | ||
| - | Has gotten input from Colin Bischoff on S4 work.\\ | ||
| - | Also a presentation from CORE.\\ | ||
