Nonzero Clkg from CambSources at very low ell even when b=0
Posted: June 28 2021
Hi,
We have found a nonzero signal for Clkg, up to 10% of the b=1 case at very low l (<20), even when b=0 in Cambsources. An example script is on github here:
https://github.com/akrolewski/cambources_test/blob/main/example_for_cosmo_coffee.py
(the repo includes the text file for the dN/dz as well). This signal appears whether I set nonlinear=True or False, and doesn't appear to be affected by the Limber parameters either. Do you know what might be going on?
