his release contains the version of the software used in the analysis presented in the paper: "High-Precision Astrometric Positioning of Near-Earth Asteroids– Via the Close Approach Method" The software provides tools for: Image reduction and centroid extraction Relative astrometry between asteroid and reference stars Determination of the closest approach time and minimum angular separation Error estimation for close-approach astrometry measurements This archived version corresponds to the code used to produce the results in the manuscript and is provided to ensure reproducibility of the analysis. Minor documentation improvements and repository organization were also included in this release.
