to_bodycentric()

BodycentricPos< F, U > siderust::to_bodycentric ( const cartesian::Position< C, F, U > &  pos, const BodycentricParams &  params, const Time< TT, JD > &  jd  )

inline

Transform a position to body-centric coordinates.

Mirrors Rust's position.to_bodycentric(params, jd).

The source center must be Geocentric, Heliocentric, or Barycentric. Calling this with Bodycentric or Topocentric as the source center will throw InvalidCenterError at runtime.

The result frame F and unit U are preserved from the source position.

Template Parameters

C	Source center (Geocentric, Heliocentric, or Barycentric).
F	Reference frame.
U	Length unit.

Parameters

pos	Source position.
params	Orbital parameters of the body to use as the new center.
jd	Julian Date for Keplerian propagation and center shifts.

Returns

BodycentricPos<F, U> — relative position plus embedded params.

Exceptions

InvalidCenterError

if the source center is not supported.

twilight_phase() [1/2]

TwilightPhase siderust::twilight_phase ( qtty::Degree  altitude )

inline

Classify the sky condition from the Sun's altitude in degrees.

Parameters

altitude

Sun altitude above the horizon (degrees, signed). Negative values mean the Sun is below the horizon.

Returns

The corresponding TwilightPhase value.

Exceptions

NullPointerError

(should never happen in normal operation).
