empyrean.SystemDescription¶

class SystemDescription(force_model, frame, encounter_timescale_divisor, relativistic, asteroids, has_bpc, perturber_origins, kernels)[source]

Bases: object

A reproducibility summary of a BuiltSystem’s frozen force model plus the kernel-identity manifest it captured.

Every field is populated — nothing is defaulted. Names the citable menu (tier, frame, GR, perturbers, BPC, kernel hashes) so a run can be reproduced and audited.

Methods

__init__(force_model, frame, ...)

Attributes

`force_model`	The frozen force-model tier.
`frame`	The frozen integration/output frame.
`encounter_timescale_divisor`	The frozen encounter-timescale divisor.
`relativistic`	Whether the post-Newtonian (EIH) relativistic correction is enabled.
`asteroids`	Whether the 16 asteroid perturbers are included.
`has_bpc`	Whether a BPC (body-fixed rotation) kernel is loaded.
`perturber_origins`	NAIF ids of the perturbing bodies included in the force model.
`kernels`	The captured kernel-identity manifest, one record per loaded file.

frame (Frame)
encounter_timescale_divisor (float)
relativistic (bool)
