With the goal of taking a step toward the construction of astrophysicallyrealistic initial data for numerical simulations of black holes, we for thefirst time derive a family of fully general relativistic initial data based onpost-2-Newtonian expansions of the 3-metric and extrinsic curvature withoutspin. It is expected that such initial data provide a direct connection withthe early inspiral phase of the binary system. We discuss a straightforwardnumerical implementation, which is based on a generalized puncture method.Furthermore, we suggest a method to address some of the inherent ambiguity inmapping post-Newtonian data onto a solution of the general relativisticconstraints.Comment: 13 pages, 8 figures, RevTex
