VolumeDistancePrior

class ssapy.correlate_tracks.VolumeDistancePrior(scale=42164172.36450565)

Bases: object

Prior on range like r^2*exp(-r/scale), preferring larger distances where there is more volume.

__call__(orbit)

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, chi=False)

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
