Resumen:
This paper investigates the possibility of eliminating the supertranslation gauge freedom at scri by the introduction of a unique set of sections, which may be understood as giving a centre of mass system of reference. Our construction depends on the properties of the physical system at the fixed retarded time defined by these sections.
