With a default option, ESTAR generates stopping powers and ranges for electrons which are the same as those tabulated in ICRU Report 37 (ICRU, 1984) for 72 materials at a standard grid of 81 kinetic energies between 10 keV and 1000 MeV. ESTAR can also calculate similar tables for any other element, compound or mixture. Furthermore it can calculate stopping powers at any set of kinetic energies between 1 keV and 10 GeV.
With a default option, PSTAR and ASTAR generate the stopping powers and ranges for protons and helium ions tabulated in ICRU Report 49 (ICRU, 1993) for 74 materials at a standard grid of 133 kinetic energies between 1 keV and 10 GeV for protons, and 122 kinetic energies between 1 keV and 1 GeV for helium ions. These databases can also calculate similar results at any other energy grid between these limits.
