Abstract
We derive the antipodal matching relations used to demonstrate the
equivalence between soft graviton theorems and BMS charge conservation
across spatial infinity. To this end we provide a precise map between
Bondi data at null infinity \mathscr{I}ℐ
and Beig—Schmidt data at spatial infinity i^0i0
in a context appropriate to the gravitational scattering problem and
celestial holography. In addition, we explicitly match the various
proposals of BMS charges at \mathscr{I}ℐ
found in the literature with the conserved charges at
i^0i0.
