The aim of this paper is to prove that a pair of analytic sets X, YCzm × Cwn is locally regularly separated with a uniform exponent α in the fibres taken over a proper projection π(z,w) = z of XY (under the assumption that XY has pure dimension): for all z ∈ π (XY) ∩ U, dist(w,Yz) ≥ const.dist(w,(XY)z)α when wXzV, where U × V is a neighbourhood of a point aXY such that π(a) is regular in π(XY). As an application of this we obtain a parameter version of the Łojasiewicz inequality for c-holomorphic mappings. Both results are a complex counterpart of the main result of [ŁW] from the subanalytic case, extended in this paper by a bound on the uniform exponent.
