Detailed Description

Transform Tags::BondiJ from the partially flat coordinates to the Cauchy coordinates.

The spin-2 quantity $\hat{J}$ transforms as

$\begin{aligned} J = \frac{1}{4 ω^{2}} ({\bar{d}}^{2} \hat{J} + c^{2} \bar{\hat{J}} + 2 c \bar{d} \hat{K}) \end{aligned}$

with

$\begin{aligned} \hat{K} = \sqrt{1 + \hat{J} \bar{\hat{J}}} \end{aligned}$
