Enumeration

NumCosmoXcorKernelCMBISWSource

Declaration 

enum NumCosmo.XcorKernelCMBISWSource

Description [src]

Where the CMB photons are placed along the line of sight. A photon that last scattered at $\chi’$ integrates the decay of the potential over $\chi < \chi’$ only, so the kernel at $\chi$ is the thin-screen one times the fraction of photons that last scatter beyond $\chi$: one below the shell, zero beyond it, and lower by the rescattered fraction between the reionization bump and the shell when reionization is included.

Members

NC_XCOR_KERNEL_CMB_ISW_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_ISW_SOURCE_VISIBILITY

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

  • Value: 1
  • Available since: 1.0
NC_XCOR_KERNEL_CMB_ISW_SOURCE_VISIBILITY_REIONIZATION

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

  • Value: 2
  • Available since: 1.0
