This video is supplementary material for the manuscript, "CoRSEER: The Calculator of Rock Surface Exposure Age and Erosion Rates for Rock Surface Luminescence dating" which is submitted in "Geochronology" journal. CoRSEER is a computational tool designed for the processing and interpretation of rock surface luminescence dating data. The software facilitates the determination of calibration parameters, estimation of apparent exposure ages, and reconstruction of erosion rates from luminescence-depth profiles measured in rock surfaces. This video serves as an instructional manual intended to guide reviewers and users through the complete operational workflow of the software. It demonstrates the full procedure, including data input, calibration, age estimation, erosion-rate analysis, and interpretation of model outputs. The video is intended to enhance transparency, reproducibility, and ease of use, thereby supporting the broader application of CoRSEER in geochronological and Earth surface process studies.
