In those papers, we derived high-order post-Newtonian expansions of the liner-in-mass-ratio corrections to gauge invariant quantites on the worldline of a point mass in a circular orbit around Schwarzschild and Kerr black holes. In the papers, due to space constraints we only gave the leading order terms in the expansion. We provide here all terms we have computed, including those which were omitted from the papers. If you find these expansions useful in your work, please cite the above papers.
