We analytically perform the transverse momentum integrations in the real corrections to the longitudinal L impact factor. The resulting integrals are Feynman parameter integrals, and we provide a MATHEMATICA file which contains the integrands. The remaining integrals are carried out numerically. We perform a numerical test, and we compute those parts of the impact factor which depend upon the energy scale s0: They are found to be negative and, with decreasing values of s0, their absolute value increases.
