Bases: popsynth.distribution.LuminosityDistribution

Lmin
__init__(seed: int = 1234, name: str = 'schechter')[source]

A Schechter luminosity function as in Schechter, Astrophysical Journal, Vol. 203, p. 297-306 (1976).

Parameters:
  • seed (int) – Random seed
  • name (str) – Name of the distribution
  • Lmin (DistributionParameter) – Minimum value of the luminosity
  • alpha (DistributionParameter) – Index of the distribution
alpha
draw_luminosity(size=1)[source]

function to draw the luminosity via an alternative method must be implemented in child class

Parameters:size –
Returns:
phi(L)[source]

The functional form of the distribution. not required for sampling :param luminosity: Luminosity
