N2 - We generate a new complete equation of state (EOS) of nuclear matter for a wide range of temperatures, densities, and proton fractions ready for use in astrophysical simulations of supernovae and neutron star mergers. Our previous two papers tabulated the EOS at over 180 000 grid points in the temperature range T=0-80 MeV, the density range nB=10-8-1.6 fm -3, and the proton fraction range YP=0-0.56. In this paper we combine these data points using a suitable interpolation scheme to generate a single EOS table on a finer grid. This table is thermodynamically consistent and conserves entropy during adiabatic compression tests. We present various thermodynamic quantities and the composition of matter in the new EOS, along with several comparisons with existing EOS tables. Our EOS table is available for download.
