commander4_sandbox

Setup:

  • Compsep + TOD

  • 2 bands at Nside=2048, lmax=6000, fwhm=10 arcmin

  • data = CMB+white noise

  • Compsep solve for CMB only, full-sky, brute-force in alm space, (S^-1 + sum_nu B^tN^-1B) s = sum_nu B^tN^-1map

  • TOD: d = PBs + n, P = diag(Npix), ie., visit each pixel just once, results in uniform rms

  • Both compsep and TOD run on two nodes each

  • Define minimal but realistic parameter files. Absolute requirements:

    • easily editable with standard text editors, such as emacs and vim
    • human readable
