Downloading the proton separation-energy data file

The entire data file of calculated one-proton separation energies S_1p and two-proton separation energies S_2p may be downloaded here The format of the file is, in FORTRAN notation (2I5,2f10), and each record contains:

Z, N, S_1p (MeV), S_2p (MeV)

If the proton separation energy can not be calculated because the ground-state masses required for the determination were not calculated then the value -20000.00 is listed.
