A4–A5: external formula comparisons

The source reports current comparisons with BdMBSH2015 at eight pairs whose approximate $q=1/\alpha$ values are

It reports relative differences at most $1.2\times 10^{-39}$, except $2.9\times 10^{-31}$ at $q=1.923$, attributed to quadrature near a small denominator. The $q=1$ limit at $\beta =0.1,0.3,0.45,0.7$ reportedly agrees to $5\times 10^{-38}$.

Against Sriramkumar2001, it reports $2\times 10^{-43}$ for the signature-translated minimal tensor and $1.2\times 10^{-44}$ for the current. It also reports exact agreement with the coupling term of SBdM2003 and agreement with its conformal term only after replacing the printed flux factor as discussed in Section sec:literature. That reported agreement does not cover the printed equation (37), which carries the extra ${\alpha }^{-2}$ corrected above.
