TL;DR: The basis for the least-squares analysis and some of its shortcomings are discussed and the tabulation should prove useful to the general user since it provides an identifiable set of values which are internally consistent to a precision of better than 0.1 part per million.

TL;DR: In this paper, the authors used the energy density method to calculate ground-state binding energies of spherical nuclei situated on the N,Z -plane inside the drip lines, for N ≤ 110 and Z ≤ 88 with a few exceptions around Z = 82 and N = 126.
