1.  Synfast resolution effects :

  • pixwin = True
  • nsimu = 50
  • Blue : synfast(ns=128, lmax=3*128-1) => anafast(lmax=3*128-1)
  • Green : synfast(ns=256, lmax=3*256-1) => ud_grade(256->128) => anafast(lmax=3*128-1)
  • Magenta : synfast(ns=256, lmax=3*128-1 ) => ud_grade(256->128) => anafast(lmax=3*128-1)
  • Red : synfast(ns=128, lmax=4*128-1 ) => anafast(lmax=3*128-1)
  • Cyan : synfast(ns=128, lmax=10*128-1 ) => anafast(lmax=3*128-1)

Spectra are then all divided by pixwin(128)^2 then plotted :

r=0.1
flat spectrum
other nside (ns8), r=0.1
