A Cross-Instrument Calibrated Production Rate Dataset and Analysis Pipeline for Interstellar Comet 3I/ATLAS

This deposit contains the calibrated volatile production-rate dataset, source-publication attribution table, fitted power-law parameters, leave-one-out robustness results, and full analysis pipeline (Jupyter notebook) underlying a cross-instrument calibration of published production-rate measurements for interstellar comet 3I/ATLAS. The dataset extends the literature compilation of Frincke & Seligman (2026) with instrument and source-publication attribution, aperture standardization, fluorescence-model harmonization, and Monte Carlo uncertainty propagation (N=10,000) for H2O, CO2, CO, Ni, and Fe (125 measurements from 12 distinct instruments). The calibrated CO2/H2O production-rate ratio (7.24 [+0.55/-0.52]) independently confirms the extreme value reported by Cordiner et al. (2025, 7.6±0.3) within 0.58σ. Full methodological documentation, including verification steps and corrections made during pipeline development, is provided in the accompanying README and data dictionary. This dataset supports a manuscript submitted to Icarus (citation to be added upon publication).
