=== Notes ===
Jamie credited with writing notes back in June\\
Action items from last week:\\
 - contact Kovac about a probe talk at Harvard S4 workshop (Shaul called)\\
 - communicate with John Carlstrom to share resources with S4 (reply pending)\\
Primary work on spectrometer has been on foregrounds\\
Spectrometer has shallow sensitivity up to several THz\\
May offer some useful information for deep imager data over narrower range of frequencies\\
What is the utility of high-frequency data given things like decorrelation?\\
The spectrometer will provide good information on dust opacity and spectral index\\
It is less clear if this knowledge will prove useful at nK sensitivities\\
Can the effect of decorrelation be included in Al's simulation?\\
Shaul:  what is the effect of mismatched angular resolution?  Is there scope for increasing it?\\
Charles:  we can't assume we will know the spectral properties of the dust\\
Question is does the spectrometer provide essential information for foreground removal?\\
Jamie:  On the time-scale of October, we should base our decision on what science each instrument would deliver.  The questions about complementarity on foregrounds is not something we are going to resolve by October, and it will be a challenge even by the end of the study.\\
Jamie:  Can a probe-class spectrometer access useful phase space on inflation?\\
Al:  Probably not, but I can quantify especially in combination with an imager.\\
Can we get a picture of MIDEX/PIXIE to get some idea of physical size?\\

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.\\
