-  * +  * Brandon describes status of MHD-Based maps: hooked up various dust models to Chang-Goo's MHD simulation. Full sky I,Q,U maps with delta-function PICO frequencies are available. They have two dust models. A modified BB in every cell, and the Draine+Hensley model. They also include synchrotron.  
 +    * The band pass integration is provided by the data processing on the pysm side. Decision is to provide 5 points per band and Andrea will interpolate.  
 +    * **Andrea will start by interpolating two bands. Time scale: two weeks.**  
 +    * **Matthieu volunteers to do analysis and to start with delta-functions** 
 +  * Matthieu is concerned about the effects of smoothing and averaging; he is running with nside=16 at the moment.  
 +  * Clem argues that if foreground separation is done at nside=16 then input maps should be at the same resolution.   
 +  * Clem says that more full sky maps are available. He recommends that we follow the same set that was done for CMB-S4.  
 +  * Chang-Goo explains that we should not expect the MHD-based models to extend to \ell>100 anytime soon.
