A revised program for plotting crater counts and determining surface ages. The software plots isochrons in cumulative, differential, R-plot and Hartmann presentations, and makes isochron fits to both cumulative and differential data. Hartmann-style piecewise production functions may also be used.
The software requires installation of the free IDL virtual machine (IDL 8.6.1. or previous versions), and runs on all common platforms.
