Description [src]

final class NumCosmo.GalaxyRedshiftObsSelGauss : NumCosmo.GalaxyRedshiftObsSel
{
  /* No available fields */
}

Gaussian population photo-z observable distribution.

A NcGalaxyRedshiftObsSel whose population observable at true redshift $z$ is Gaussian, $\mathrm{obs} \sim \mathcal{N}(z, \sigma_z)$ with $\sigma_z = \sigma_0 (1 + z)$ and a single population-scatter parameter $\sigma_0$. Currently shares the Gaussian-integral math with the per-galaxy NcGalaxyRedshiftObsGauss, but is a distinct abstraction free to become a scatter mixture as its assumptions diverge.

Methods inherited from NcGalaxyRedshiftObsSel (4)

nc_galaxy_redshift_obs_sel_eval

Computes the population-level probability density of the observable at value obs and fixed true redshift z, i.e. the density whose integral over a window is nc_galaxy_redshift_obs_sel_window_mass(). Used by the binning calculator to build the marginal observable distribution $P(z_p)$.

nc_galaxy_redshift_obs_sel_free

Decreases the reference count of gsdrop by one.

nc_galaxy_redshift_obs_sel_ref

Increases the reference count of gsdrop by one.

nc_galaxy_redshift_obs_sel_window_mass

Computes the population-level probability mass of the observable in the window $[\mathtt{obs_lo}, \mathtt{obs_hi}]$ at fixed true redshift z, i.e. the fraction of the population at z whose observable falls in the window. This is the selection/normalization factor used by the binning calculator.
