NumCosmoGalaxyRedshiftBinninglsst_srd_edges

Declaration [src] 

NcmVector*
nc_galaxy_redshift_binning_lsst_srd_edges (
  NcGalaxyRedshiftPopLSSTSRDType type,
  NcGalaxyRedshiftPop** population,
  NcGalaxyRedshiftObsSel** observable_population
)

Description [src]

Computes the LSST SRD tomographic photo-z bin edges for type and hands back the matching population + Gaussian observable models (both configured for type) via the out-parameters. The edges follow the LSST DESC SRD recipe:

  • Lens (Y1, Y10): linearly spaced edges over $[0.2, 1.2]$ (Y1: 5 bins, Y10: 10 bins), $\sigma_0 = 0.03$.
  • Source (Y1, Y10): equal-area edges up to $z_p = 3.5$ (5 bins), $\sigma_0 = 0.05$; computed by inverting the marginal $P(z_p)$.

The returned edges feed nc_galaxy_redshift_binning_compute_dndz() (per consecutive pair) with the handed-back models. This is a factory: it holds nothing.

Parameters

type

Type: NcGalaxyRedshiftPopLSSTSRDType

A NcGalaxyRedshiftPopLSSTSRDType.

population

Type: NcGalaxyRedshiftPop

The LSST SRD population model for type.

The argument will be set by the function.
The caller of the function takes ownership of the returned data, and is responsible for freeing it.
observable_population

Type: NcGalaxyRedshiftObsSel

A Gaussian photo-z observable with the per-type scatter $\sigma_0$.

The argument will be set by the function.
The caller of the function takes ownership of the returned data, and is responsible for freeing it.

Return value

Type: NcmVector

A NcmVector with n_bins + 1 photo-z edges.

The caller of the function takes ownership of the data, and is responsible for freeing it.
