Detailed Description

Compute \(\bar{J}\).

Note
Computing \(\bar{J}\) should be unnecessary in most execution procedures, as all quantities should be derived from \(J\) and its derivatives followed by explicit conjugation operations, which are expected to be sufficiently cheap to avoid the storage cost of recording the conjugates. The exception is caching for certain spin-weighted derivatives of products
