ParetoHomogeneousSphericalPopulation
(Lambda: float, Lmin: float, alpha: float, r_max: float = 5, seed: int = 1234)[source]¶ Bases:
popsynth.populations.spatial_populations.SphericalPopulation
-
__init__
(Lambda: float, Lmin: float, alpha: float, r_max: float = 5, seed: int = 1234)[source]¶ A population built on the
ConstantSphericalDistribution
spatial distribution and theParetoDistribution
luminosity distribution.Parameters: - Lambda (float) – Density per unit volume
- Lmin (float) – Minimum value of the luminosity
- alpha (float) – Index of the luminosity distribution
- r_max (float) – Maximum distance
- seed (int) – Random seed

(r0: float, a: float, rise: float, decay: float, peak: float, Lmin: float, alpha: float, r_max: float = 5, seed: int = 1234, is_rate: bool = True)[source]¶ A population built on the
SFRDistribution
spatial distribution and theParetoDistribution
luminosity distribution.Parameters: - r0 (float) – Local density in units of Gpc^-3
- a (float) – Offset at z=0
- rise (float) – Rise at low z
- decay (float) – Decay at high z
- peak (float) – Peak of z distribution
- Lmin (float) – Minimum value of the luminosity
- alpha (float) – Index of the luminosity distribution
- r_max (float) – Maximum redshift
- seed (int) – Random seed
- is_rate (bool) – True if modelling a population of transient events,
False if modelling a population of steady-state objects.
Affects the
time_adjustment
method used in cosmo calculations. Default is True.
