Astrometry.SOFA.fad03 — Function
fad03(Δt::Float64)

Fundamental argument, IERS Conventions (2003): mean elongation of the Moon from the Sun.

Input

  • Δt – TDB, Julian centuries since J2000.0 (Note 1)

Output

  • D – D, radians (Note 2)

Note

  1. Though Δt 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 is from Simon et al. (1994).
