June 06 - CMB, Websky and LensPix

I took the map from the Websky simulation (those on this website) and did :

- lensing of unlensed CMB with kappa from Websky, with two different parameters for LensPix: the old and one of the best obtained according to the results of yesterday;

- lensing of unlensed CMB with kappa from Websky, using Joel's & Alex's code.

Then I plotted the relative difference for each lensed map (with filter), the result is below.

There is a difference between the Websky map and the other, if the theory calculus is the right one, with no surprise, the best parameter for LensPix (interpolation factor = 6) is near the theory's computation.

I will compare those results with CAMB later, I just need to have the exact parameters used in the Peak Patch simulation, according to CAMB nomenclature.
