popsynth.distributions.log10_normal_distribution module

class popsynth.distributions.log10_normal_distribution.Log10NormalDistribution(seed: int = 1234, name: str = 'log10norm')

Bases: popsynth.distribution.LuminosityDistribution

__init__(seed: int = 1234, name: str = 'log10norm')

A log10-normal luminosity function

Log10Normal(mu, tau)

Parameters:

• seed (int) – Random seed
• name (str) – Name of the distribution
• mu (DistributionParameter) – Mean of the log10 normal
• tau (DistributionParameter) – Standard deviation of the log10 normal

draw_luminosity(size=1)

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

Parameters:size – Returns:

mu

phi(L)

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

tau
