July 20 - Cal-Sky - CIB

Ran Cal-Sky with fields, with a box of redshift depth equal to 0.5. Computed slices of CIB, with a delta z of 0.1. Lensed those slices by kappa shells from redshift 0 to zi, where CIB is from zi to zi+0.1.

There is a mismatch between theoretical computation (lenspower) and simulation (lenspix).

Ran the same thing but with both now GRF, simulated from the Cal-Sky power spectrum of CIB/kappa with Healpy

There is still a mismatch.

Here is the statistics of kappa fields

and the same with GRF

Finally, theoretical computation of kappa power spectrum (pycamb) vs cal-sky simulation
