NumCosmoXcorKernelCMBLensingSource

Declaration 

enum NumCosmo.XcorKernelCMBLensingSource

Description [src]

Where the CMB photons are placed along the line of sight. The thin screen is the usual single source plane at $z_$. The visibility source integrates the lensing efficiency over the last-scattering shell, whose width in comoving distance is about one percent of $\chi_$. With reionization, the tenth of the photons that last scatter at $z \sim 10$ are lensed only by the structure in front of them: between the reionization bump and the shell the kernel is lowered by that fraction, while at low redshift, where every source is far away, the two visibility sources agree.

Members

NC_XCOR_KERNEL_CMB_LENSING_SOURCE_THIN_SCREEN

Every CMB photon last scatters at the decoupling redshift of the NcDistance.

  • Value: 0
  • Available since: 1.0
NC_XCOR_KERNEL_CMB_LENSING_SOURCE_VISIBILITY

The sources follow the visibility function of the NcXcorKernelCMBLensing:recomb object over the last-scattering shell, normalized to unit integral there.

  • Value: 1
  • Available since: 1.0
NC_XCOR_KERNEL_CMB_LENSING_SOURCE_VISIBILITY_REIONIZATION

The sources follow the full visibility function, the reionization bump included.

  • Value: 2
