Checking forecasting outputs

This should be run for the test case for S4+Planck. This is T/E/B/kappa. No clusters or BAO at this point (can be posted in other entries though). Settings described here and here:

  • S4 = single channel (e.g. 150 GHz) at 1 uK/amin in T and 1.4uK/amin in P, 3 arcmin resolution.
  • White noise, no FG inflation
  • S4 T/E/B/k over 40% of sky, 30<ell < lmax
  • Planck TT/TE/EE from 30<l<2500 over additional 20% of sky. Can use these 'Planck-pol' specs for noise:File:Planck pol.pdf
  • Planck TT at l<30 over 80% of sky
  • Tau prior 0.06+-0.01
  • lmax(TT)=3000 unless explicit foreground cleaning is done in code for kSZ etc
  • lmax(TE,EE)=5000 unless explicit foreground cleaning done in code
  • kk reconstructed from 30<l<lmax using MV estimate
  • quadratic estimator for lensing, ideally with iterative delensing
  • Gaussian likelihood neglecting T/E/k covariance is ok, but non-Gaussian better
  • non-linear power spectrum for kk, e.g. ok to use halofit in CAMB
  • if easy to do, use pivot k=0.05
  • don't need to use same fiducial, but useful to note what you have used.

Notes

  • From Jo: got these errors for Planck-alone for LCDM: 0.00017, 0.0014, 0.00047, 0.039, 0.004, 0.01.
