AB: The upcoming launch of the Interstellar Boundary Explorer (IBEX) promises a unique data set of heliospheric energetic neutral atoms (ENAs), rich with information about the global dynamics of the termination shock and heliosheath. We have developed a suite of tools to predict synthetic ENA flux from the internal energy, density, and bulk flow derived from large-scale magnetohydrodynamic simulations of the heliosheath, creating a visualization framework for ENA flux maps as well as making predictions for the IBEX mission. In the future these tools will be critical for interpreting the implications of IBEX observations. The impact of the ion distribution function is also explored in the context of ENA flux maps. Studies from ACE, WIND, and Ulysses have shown the solar wind ion population has a power law tail in suprathermal velocities between 2-10 times the solar wind speed. This solar wind characteristic is found to increase the predicted flux by more than an order of magnitude at the highest IBEX energies, with less but considerable impact at lower energies.
