Detailed Description

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

Details

The spin-2 quantity \(\hat J\) transforms as

\begin{align*}J = \frac{1}{4 \omega^2} (\bar d^2 \hat J + c^2 \bar{\hat J} + 2 c \bar d \hat K ) \end{align*}

with

\begin{align*}\hat K = \sqrt{1+\hat J \bar{\hat J}} \end{align*}
