pub fn fame03(t: f64) -> f64
Expand description

Fundamental argument, IERS Conventions (2003): mean longitude of Mercury.

Status: canonical model.

Given: t f64 TDB, Julian centuries since J2000.0 (Note 1)

Returned (function value): f64 mean longitude of Mercury, radians (Note 2)

Notes:

  1. Though t is strictly TDB, it is usually more convenient to use TT, which makes no significant difference.

  2. The expression used is as adopted in IERS Conventions (2003) and comes from Souchay et al. (1999) after Simon et al. (1994).
