Notes.

^(a)

The prior bounds of f correspond to a period range between 1d and 1 yr.

^(b)

The bounds of V are given by the section of the RV ranges measured for primary and secondary, with the latter extended by one corresponding measurement uncertainty on both sides.

^(c)

The upper bounds of K₁ and K₂ are given by half the measured RV span of the corresponding component, plus one measurement uncertainty.
