CircVelocityPrior

class ssapy.correlate_tracks.CircVelocityPrior(sigma=0.19804205158855578)[source][source]

Gaussian prior that log(GM/r/v^2) = 0.

Parameters:: sigma (float) – Prior standard deviation on log(GM/r/v^2), dimensionless.

__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, chi=False)[source][source]

Return log prior probability of given orbit.

Parameters:

orbit (Orbit) – The given orbit.
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
