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 | | |
