 +Exgal sim updates (Marcelo) 
 + 
 +CMB halo lensing (Jim and Jean-Batiste)

 +Exgal simulated maps update (Marcelo). 
 +Peak patch method paper to come out soon , Fast but memory intensive 
 +1/8 of sky out to z = 4.5, without repeats 
 +Sims on NERSC Please add link/path 
 +CIB is now in for 60 different band passes (with CMB probe bands please check!) 
 +Lensing, SZ also included 
 + 
 +Should we include neutrinos? 
 +Including variance into the gas profiles? 
 +Secondary Affects  
 + 
 +Action item: 
 +Please check the bands for Probe 
 +Maps of each component  
 + 
 +Jim 
 + 
 +CMB halo lensing forecast for 4 arcminute beam and noise 1 muK - arcmin 
 +EB is not sensitive to resolution, TT is, so going to smaller aperture help reduce the noise in the TT  
 +Almost as good as CMB-S4 EB is actually very similar. 
 + 
 +How did you choose the Beam size? 
 +-Pulled out of the air. We need an actually calculation. 
 + 
 +Action items:  
 +Colin will produce foreground cleaned noise spectra for the lens-ers 
 +Remove the two high frequency bands 
 + 
 +Shaul 
 + 
 +New specs are for Imager + Spectrometer which would likely degrade the Imager at fixed cost. The Spectrometer would be a mini PIXIE, looking into cost. 
 + 
 +The new imager has a 50 cm aperture. Specs are posted and we will focus on the specific option, which we will call the nominal 50 cm. 
 + 
 +Time scales are short! The EC would like to know by next week so if you can run your forecasting codes by next week that would most appreciated. 
 + 
 +What science are we getting from the spectrometer? 
 + 
 +Action items: 
 +Post the Nominal Specs 
 +Get information from the spectrometer
