Abstract

This project presents phase curve determinations for over 300,000 asteroids using the ATLAS Solar System Catalog V2 (SSCAT-2) in two filters: orange (301,272 asteroids) and cyan (280,953 asteroids). Among these, a subset of 3,345 (orange) and 492 (cyan) asteroids have phase curve uncertainties below 15%. Using a simple model accounting only for apparition effects, we achieved results consistent with more computationally intensive methods.
