AttitudeCharacterization

Result of a satellite-stability characterization run.

Returned by characterize_stability and the related characterize_stability_gregory_loredo / characterize_stability_quasi_periodic_gp methods. The log_odds attribute is populated only by the Bayesian methods; the string-length method does not produce a log-odds score.

Attributes:

Name	Type	Description
is_stable	bool	True when no period was detected (rotationally stable); False when a period was detected (tumbling).
period_sec	Optional[float]	Detected rotation period [s], or None when no period was detected.
log_odds	Optional[float]	Log Bayes factor of the best period vs. the no-periodicity baseline [nats]. None for the string-length method; float for the Bayesian methods (Gregory-Loredo, quasi-periodic GP).

is_stable property

True when no period was detected (rotationally stable).

False when a period was detected (the satellite is tumbling).

log_odds property

Log Bayes factor of the best period vs. the no-periodicity baseline [nats].

None for the string-length method (characterize_stability); float for the Bayesian methods (characterize_stability_gregory_loredo, characterize_stability_quasi_periodic_gp).

period_sec property

Detected rotation period [s], or None when no period was detected.
