*Definition [#e9d36c4b] A subset Y of a topological space X is said to be countably 1-paracompact if for every countable open cover U of X, there exists a collection V which satisfies: ++V consists of open subsets of X; ++V covers X; ++V refines U; ++V is [[locally finite]] at Y. *Remark [#ade59a2f] -See [[1-paracompact]]. *Reference [#u6cc3a79] K.P.Hart, J.
