AreaPrior

class ssapy.rvsampler.AreaPrior(mean=0, sigma=2)[source][source]

Bases: object

Gaussian prior on log10(area) of object.

Parameters:

  • mean (float) – mean of log10(area)

  • sigma (float) – standard deviation of log10(area)

mean, sigma
__call__(orbit)[source][source]

Returns log prior probability of given orbit.

Methods Summary

__call__(orbit[, distance, chi])

Return log prior probability of given orbit.

Methods Documentation

__call__(orbit, distance=None, chi=False)[source][source]

Return log prior probability of given orbit.

Parameters:

  • orbit (Orbit) – The given orbit.

  • distance (float) – Distance between object and observer (m)

  • chi (bool) – If True, return chi corresponding to log probability, rather than log probability.

Returns:

logprior – The log of the prior probability for given orbit.

Return type:

float
