EPrior

class ssapy.rvsampler.EPrior(emean, esigma)

Bases: object

Gaussian prior on orbit eccentricity e.

Parameters:

• emean (float) – Prior mean on e.

• esigma (float) – Prior standard deviation on e.

eMean

eSigma

__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, optional) – Distance between object and observer (m) [not used]

• chi (bool) – If true, return chi rather than ln(prob)

Returns:

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

Return type:

float
