Oct 31, 2018 - Statistics of George's maps

George produced CIB and kappa maps, with shells in comoving distance, with 20 equally spaced shells from chi=0 to chi=8000 (z=4.6).

The maps can be found at /scratch/r/rbond/gstein/peak-patch-runs/current/jason_cib_lensing/maps/

We looked into the auto and cross spectra:

Comments:

• CIB at small scales gets most of the contributions from intermediate redshift; at large scales nearest structures contribute (both expected properties)
• CIB power is mostly featurless, which means that the lensing effects will likely not be very pronounced
• There is a significant cross-correlation, this can lead to difference in lensed power spectra between Lenspix and CAMB
• Kappa power grows with z, which makes sense
