   * General agreement on wording of E-mail for community participation in working groups.  __Rafael to send brief description__ to Shaul for broader working group including non-inflationary fundamental physics (neutrino mass, Neff).   * General agreement on wording of E-mail for community participation in working groups.  __Rafael to send brief description__ to Shaul for broader working group including non-inflationary fundamental physics (neutrino mass, Neff).
   * Question for data challenge: What units should we use?  Thermodynamic temperature units will pose a problem when trying to combine with channels above 1 THz from a spectrometer.  Existing S4 material on disk is already in units mK thermodynamic temperature.  Don't want to force massive rework, but don't want to prevent analysis of potential benefits from spectrometer data from higher frequencies.  __**Action:** Will sort offline with Julian/Clem.__    * Question for data challenge: What units should we use?  Thermodynamic temperature units will pose a problem when trying to combine with channels above 1 THz from a spectrometer.  Existing S4 material on disk is already in units mK thermodynamic temperature.  Don't want to force massive rework, but don't want to prevent analysis of potential benefits from spectrometer data from higher frequencies.  __**Action:** Will sort offline with Julian/Clem.__ 
- +  * Amy reviewed initial aperture analysis.  Assume Falcon-9 launch vehicle, which has 4.6 m usable fairing diameter.  Corresponding mirror effective aperture is 1.2 m to 1.4 m unless we go to deployables.  Going to optics significantly larger than CoRE will require significant cost savings from some other subsystem.  Is there a science driver (de-lensing?) that strongly pushes case for apertures significantly larger than 1.2 meters?
