Bases: object

Result of orbit determination — returned by both determine() (full IOD + DC pipeline) and refine() (Bayesian-prior fit against an existing orbit + covariance).

Mirrors the Rust wrapper’s empyrean::DetermineResult.

Methods

__init__(orbit, observations, summary, ...)

Attributes

`orbit`	Fitted orbit.
`observations`	Per-observation residuals + rejection / influence diagnostics.
`summary`
`iterations`
`update_norm`
`converged`
`covariance`	Fitted 6×6 state covariance, in `covariance_representation`.
`covariance_representation`
`covariance_9x9`	Full 9×9 covariance over (state, A1, A2, A3) when solving for non-grav.
`non_grav_delta`	Cumulative non-grav corrections (ΔA1, ΔA2, ΔA3) when present.
`rejection_passes`
`num_oppositions_fit`
`force_model_used`
`solve_for_used`
`acceptability`
`station_biases`	Per-station fitted nuisance biases when `ODConfig.fit_station_biases` was active.
`solved_covariance`	Full tagged solved-parameter covariance when the fit solved any wide axis (Marsden / DT / AMRAT / thrust).
`dt_delta`	Cumulative non-grav time-delay correction ΔDT (days), when DT was solved.
`amrat_delta`	Cumulative SRP AMRAT correction (m²/kg), when AMRAT was solved.
`thrust_delta_m_per_s`	Per-segment fitted thrust Δv (m/s), shaped `(k, 3)` and expressed in `dv_frame`.
`dv_frame`	Integration frame the thrust Δv components are expressed in (`"icrf"` / `"eclipticj2000"` / `"itrf93"`).
`photometry`	Post-OD photometric solution when photometry was requested and ran.
`covariance_trust`	Event-aware trust verdict on the delivered covariance.

orbit: CartesianOrbits | KeplerianOrbits | CometaryOrbits | SphericalOrbits: Fitted orbit. Coordinate flavor matches ODConfig.output_representation.

observations: ObservationResults: Per-observation residuals + rejection / influence diagnostics.

summary: ResidualSummary

iterations: int

update_norm: float

converged: bool

covariance: ndarray: Fitted 6×6 state covariance, in covariance_representation.

covariance_representation: CovarianceRepresentation

covariance_9x9: ndarray | None: Full 9×9 covariance over (state, A1, A2, A3) when solving for non-grav.

non_grav_delta: ndarray | None: Cumulative non-grav corrections (ΔA1, ΔA2, ΔA3) when present.

rejection_passes: int

num_oppositions_fit: int

force_model_used: ForceModelTier

solve_for_used: SolveForParams

acceptability: AcceptabilityReport

station_biases: StationBiases: Per-station fitted nuisance biases when ODConfig.fit_station_biases was active. Empty quivr table otherwise.

solved_covariance: SolvedCovariance | None: Full tagged solved-parameter covariance when the fit solved any wide axis (Marsden / DT / AMRAT / thrust). None for a state-only fit — read it, not the width, to locate solved parameters.

dt_delta: float | None: Cumulative non-grav time-delay correction ΔDT (days), when DT was solved. None otherwise.

amrat_delta: float | None: Cumulative SRP AMRAT correction (m²/kg), when AMRAT was solved. None otherwise.

thrust_delta_m_per_s: ndarray | None: Per-segment fitted thrust Δv (m/s), shaped (k, 3) and expressed in dv_frame. None when no thrust was solved.

dv_frame: str | None: Integration frame the thrust Δv components are expressed in ("icrf" / "eclipticj2000" / "itrf93"). None when no thrust was solved.

photometry: PhotometryResult | None: Post-OD photometric solution when photometry was requested and ran. None otherwise.

covariance_trust: CovarianceTrust | None: Event-aware trust verdict on the delivered covariance. None when the call path ran no trust gate — absence of a verdict is not trust.
