In science:

It is clear from this expression that the energy depends on the parameter η and if this parameter equals zero then the tetrad (29) will coincide with the diagonal form of the tetrad (36) and the associated energy will be the same as that obtained before .

Thus the total energy will coincide with that of the Schwarzschild solution, since the metric associated with the tetrad (29) in this case gives the Schwarzschild metric.
