Wrapper scripts and control functions: | ||

get_al_be_age.m | Function that actually carries out exposure age calculations. Accepts a package of error-checked input data from the wrapper script, does age calculations, returns package of results. | |

get_al_be_erosion.m | Function that actually carries out erosion rate calculations. Accepts a package of error-checked input data from the wrapper script, does age calculations, returns package of results. | |

make_al_be_consts_v22.m | Script that assembles and saves the constants data file used by nearly all the above functions. Requires the data file PMag_Mar07.mat. | |
