EquinoctialExEyPrior

class ssapy.rvsampler.EquinoctialExEyPrior(sigma)

Bases: object

Gaussian prior on equinoctial ex and ey, favoring ex = ey = 0.

Parameters:

sigma (float) – standard deviation on ex and ey

sigma

__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=None, 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
