| + | 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. | ||
| + | |||

| + | Colin will produce foreground cleaned noise spectra for the lens-ers | ||
| + | Remove the two high frequency bands | ||

| + | 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 | ||
