Nov 8, 2018 - Lensing effect on CIB power spectra

With unlensed CIB maps and kappa maps, we can run Louis's code to get lensed CIB maps.

Fractional change to the power spectra as a function of redshift is below

Summing CIB signal over all slices gives us total unlensed/lensed CIB signal. Overall, the change in the power due to lensing is plotted here (error bars are error of the mean in the bin). Nothing in there.

As pointed out in the previous post that used wrongly lensed CIB, we find that above [math]\displaystyle{ \ell \approx 2000 }[/math] CIB signal appears to be dominated by the CIB sources closest to us.
