We consider weak (''Leray'') solutions to the stationary Navier-Stokes systemwith Oseen and rotational terms, in an exterior domain. It is shown thevelocity may be split into a constant times the first column of the fundamentalsolution of the Oseen system, plus a remainder term decaying pointwise nearinfinity at a rate which is higher than the decay rate of the Oseen tensor.This result improves the theory by M. Kyed, Asymptotic profile of a linearizedflow past a rotating body, Q. Appl. Math. 71 (2013), 489-500.
