  In previous articles we outlined a subtraction scheme for regularizing
doubly-real emission and real-virtual emission in next-to-next-to-leading order
(NNLO) calculations of jet cross sections in electron-positron annihilation. In
order to find the NNLO correction these subtraction terms have to be integrated
over the factorized unresolved phase space and combined with the two-loop
corrections. In this paper we perform the integration of all one-parton
unresolved subtraction terms.
