Observational Audit Cites Every Source - Observational Astrophysics: Distance, Flux, Transits, and Spectra Step by Step

The capstone audit accepts only a closed chain of measurement sources. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The audit cites every measurement source by role

The final audit has parallax, flux, transit, spectral, and period sources, with accepted bit 1.

\text{sources}=\{\text{parallax},\text{flux},\text{transit},\text{spectral},\text{period}\},\quad accepted=1

Hidden refs bind the displayed roles to exact values

The hidden source refs bind distance index 5, flux 4, transit depth 1/25, shift 1/6, and period ratio 1/2.

d=5,\quad F=4,\quad depth=\tfrac{1}{25},\quad shift=\tfrac{1}{6},\quad period=\tfrac{1}{2}
