A program for modeling the flight of a small iron meteoroid through the atmosphere. The input file contains meteoroid parameters such as initial mass, velocity, temperature and altitude, zenith distance and droplet size distribution of the molten material. The program then models the physical processes associated with the atmospheric passage as described in Čapek, D., Koten, P., Borovička, J., Vojáček, V., Spurný, P., Štork, V.: “Small iron meteoroids. Observation and modeling of meteor light curves.” A&A 625 (2019). The output is a table containing individual heights above the surface and the corresponding magnitude, velocity, acceleration, size, temperature at the surface and in the middle of the meteoroid, atmospheric density, acceleration, time and gas flow parameters. The program is written in Fortran 90 and uses the tridag2, four1, sort2, laguer, spline and splint subroutines from Numerical Recipes.
