                                   rct2-16.txt : react and sep energies,  part 2
   A fourth file  is the "Rounded" version of the atomic mass table (the first file)

   All files are 3436 lines long with 124 character per line.
       Headers are 39 lines long.
   Values in files 1, 2 and 3 are unrounded copy of the published ones
   Values in file  4          are exact     copy of the published ones

                      in particular "Mass Excess" and "Atomic Mass" values are given now, when necessary,
                      with 5 digits after decimal point.
                decimal point is replaced by # for (non-experimental) estimated values.
