Query: The weak-field-limit solution for Kerr black hole in radiation gauge   In this work we present the solution for a rotating Kerr black hole in the
weak-field limit under the radiation gauge proposed by Chen and Zhu [Phys. Rev.
D83, 061501(R) (2011)], with which the two physical components of the
gravitational wave can be picked out exactly.
