Specialization for the spin-weighted derivative \(\bar{\eth}\).
The implemented equation is:
\[ \bar{\eth} F = \bar{\eth}^\prime F - (1 - y) \frac{\bar{\eth} R}{R} \partial_y F, *\]
where \(\bar{\eth}\) is the derivative at constant Bondi radius \(r\) and \(\bar{\eth}^\prime\) is the derivative at constant numerical radius \(y\).
