GSPT-Based Critical Dynamics of 3I/ATLAS: Complete Dataset and Reproduction Package

Zenodo Metadata Description for 3I/ATLAS GSPT Regenerated Data Package===================================================================== Title:Regenerated Data Package for the GSPT Analysis of Interstellar Object 3I/ATLAS Description:This Zenodo deposit contains the complete regenerated data package used in theGeometric Singular Perturbation Theory (GSPT) analysis of the interstellar object3I/ATLAS (C/2025 N1). It includes raw photometry, enhanced geometry, derived activitydiagnostics, GSPT manifolds, anomalous events, appendices, documentation, and a reproduction Python script. The package is structured to support full transparency and computational reproducibility for the accompanying ApJL Letter. Contents:- photometry/: COBS, ATLAS, TESS raw photometry- geometry/: JPL/Horizons enhanced geometry- derived/: unified lightcurve, ε_eff, ε(r), x_phase, cleaned dataset- figures_data/: CSV files behind manuscript figures- gspt_manifolds/: critical & slow manifolds, normal eigenvalues- events/: anomalous photometric events- docs/: dataset documentation, derivations, appendices, manuscript drafts- scripts/: Python reproduction script Keywords:3I/ATLAS, interstellar object, GSPT, geometric singular perturbation theory, ε(r),critical manifold, slow manifold, photometry, dynamical systems, reproducible science License:CC-BY 4.0 Related Publication:ApJL Letter — A Data-Driven GSPT Analysis of Interstellar Object 3I/ATLAS
