1. C2 apodization on xpol
- using C2 apodization from NaMaster package
- Nside=128, fwhmdeg = 0.5 + pixwin, r=0.001, fsky=0.7 (planck/Litebird-like mask)
- Apodizations are \theta^* = [0.6, 0.8, 1.0, 2.0, 3.0, 4.0, 5.0, 7.0, 10.0] from red to blue.
\theta^* = 0.6 | \theta^* = 5.0 | \theta^* = 10.0 |
| | |
| 0.0 muK.arcmin | 50.0 muK.arcmin |
spectum mean | | |
spectum residues R_\ell = (\hat C_\ell - C_\ell)/(\sqrt{\sigma^2(C_\ell)/ n_{simu} } ) | | |
\sigma(C_\ell^{\theta^*})/\sigma(C^{\theta^*=0.6}_\ell) | | |
\sigma(D_\ell^{\theta^*}) | | |
special case sigma cl : apo = [0.6, 7.0, 10.0] = [blue, red, green] | | |
- observations :
- no bias, as small as can be the apodization lenght ( \theta^*=0.6 ). Lower apodization lenght break NaMaster routines.
- high apodization lenght usefull for BB variance with low noise only.
