Short summary
We developed an open-source program that estimates how long a rock surface has been exposed and how rapidly it has eroded from changes in luminescence with depth. The program objectively normalises measured profiles, simulates signal bleaching and erosion, and reports uncertainty. Tests using published data produced results consistent with previous studies and improved reproducibility, supporting more reliable reconstruction of recent landscape change.
