TI - Kerr-Schild metrics revisited. Pt. 1. The ground state
AB - The particular way Kerr-Schild metrics incorporate a congruence of null curves in space-time is a sure source of fascination. The Kerr-Schild pencil of metrics g{sub ab}+{Delta}l{sub a}l{sub b} is investigated in the generic case when it maps an arbitrary vacuum space-time with metric g{sub ab} to a vacuum space-time. The theorem is proved that this generic case does not contain the shear-free subclass as a smooth limit. It is shown that one of the Kota-Perjes metrics is a solution in the shearing class.
