PyOutfit(ephem: str, error_model: str)

pyOutfit: Python bindings for the Outfit orbit-determination engine.

Provides a thin, Pythonic surface around the Rust core Outfit, exposing: - High-precision ephemerides configuration (e.g., DE440). - Observatories management (MPC code lookup, listing). - Gauss-based initial orbit determination (via other types in this module).

PARAMETER DESCRIPTION

ephem

Ephemerides selector in the form "{source}:{version}". The source must be "horizon" (legacy JPL DE binaries) or "naif" (NAIF SPK/DAF kernels). The version must be a supported DE series label recognized by Outfit. Common values include "DE430", "DE431", "DE440", "DE441", and "DE442". Examples include "horizon:DE440" and "naif:DE441". The ephemeris file is resolved into the user cache and opened lazily; when downloads are enabled at build time, a missing file may be fetched automatically, otherwise an error is raised.

TYPE: str

error_model

Astrometric error model. Accepted values are "FCCT14", "VFCC17", and "CBM10". Unknown strings default to "FCCT14". The model provides per-site RA/DEC bias and RMS used during orbit determination.

TYPE: str

RETURNS	DESCRIPTION
`PyOutfit`	An initialized `PyOutfit` environment.

add_observer

add_observer(observer: Observer) -> None

Register an Observer in the current environment.

PARAMETER	DESCRIPTION
`observer`	The observatory/site descriptor to register. TYPE: `Observer`

show_observatories

show_observatories() -> str

Render a human-readable list of currently known observatories.

RETURNS	DESCRIPTION
`str`	A formatted `str` (table/list) of observatories.

get_observer_from_mpc_code

get_observer_from_mpc_code(code: str) -> Observer

Lookup an Observer from its MPC code.

PARAMETER	DESCRIPTION
`code`	MPC observatory code, e.g. "807". TYPE: `str`

RETURNS	DESCRIPTION
`Observer`	an `Observer` handle usable with `add_observer`.
