 +Attendees: Gianfranco, Sebastian, Shaul, Marcelo, Jim, Colin, Alex, Nick
 +
 +Agenda:
 +
 +Exgal sim updates (Marcelo)
 +
 +CMB halo lensing (Jim and Jean-Batiste)
 +https://zzz.physics.umn.edu/ipsig/_media/screen_shot_2017-10-10_at_3.46.49_pm.png
 +
 +New Imager specs (Shaul)
 +
 +WG Update (Nick)

 +
 +__Minutes__
 +
 +Marcelo
 +
 +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
