Chang'e-6 nearby craters within a 1 km diameter and the simulated craters

CE6_NAC_1km_Circle.txt : text file for the craters within a 1-kilometer diameter circle across the CE-6 landing site

producd craters.zip :  the generated primary and secondary craters in the four period models (2.4-3.0 Ga). In the each numpy file, the data are saved in a 6*n materix, including the craters diameter, x&y position in pixel, craters indentifier (1 for primary and <1 for the secondary),  generated time steps and their impactors,  sequentially.
