  3. theorem OAI.RegularPointCoordinates.regular_pair_direction line 32

    Source documentation

    The pairing is constructed from the actual radial derivatives. Every smallness premise here is an explicit scalar bound on the already constructed source envelopes; no direction or mass estimate is assumed.
