make_al_be_consts_v12.m

Syntax:

make_al_be_consts_v12

This function has no arguments or outputs. It creates a structure called al_be_consts that contains all the constants relevant to the exposure age and erosion rate calculations, and saves it as a .mat file. All fields are numerical values except for version, which is a string. The fields are:
