  The connection between the Bondi-Sachs (BS) and the Newman-Penrose (NP)
framework for the study of the asymptotics of the gravitational field is done.
In particular the coordinate transformation relationg the BS luminosity
parameter and the NP affine parameter is obtained. Using this coordinate
transformation it is possible to express BS quantities in terms of NP
quantities, and to show that if the Outgoing Radiation Condition is not
satisfied then the spacetime will not decay in the way prescribed by the
Peeling theorem.
