=== Notes (Shaul) ===

• Ragnhild on vacation
• MR is now reporting results for model 98! (.pdf).
  • There are foreground residuals that are significant relative to 5e-4, see pages 15 and 18 in the pdf.
  • There is strong sensitivity to the higher frequency bands, see page 32.
  • SH: how is S4 doing with this model
  • MR: Need to check the maps and the mask being used. Perhaps can optimize the mask, but smaller patches will lead to higher noise. Worth trying.
  • Is the model even consistent with current constraints on the sky?
  • Question: slide 15, why is there a break in the noise at \ell= 700
  • Note: MR had done r=0.003 only on models 91,92 so far
• Kris: needs to extrapolate to higher frequency bands . He is incorporating spectral index map.
