Code and Data for: Evidence Against Primordial Mass Segregation in Young Open Clusters: A Bayesian Multi-Scale Analysis of 3,881 Gaia DR3 Clusters

This repository contains the source code and processed data tables supporting the findings in the manuscript "Evidence Against Primordial Mass Segregation in Young Open Clusters: A Bayesian Multi-Scale Analysis of 3,881 Gaia DR3 Clusters", submitted to The Astronomical Journal (AJ). Contents:* analysis_pipeline.py: The Python script used for Bayesian deconvolution, metric calculation, and figure generation.* final_metrics_complete.csv: The calculated spatial and kinematic metrics for the 3,881 clusters analyzed.* hunt24.csv: The master catalog file.* hunt24.zip: The compressed cluster member data. Usage:1. Unzip 'hunt24.zip' into the same directory as the script.2. Ensure 'hunt24.csv' is in the directory.3. Run 'python analysis_pipeline.py'. Data Source:This work makes use of the open cluster catalog provided by Hunt & Reffert (2024) based on Gaia DR3 data.Reference: Hunt, E. L., & Reffert, S. (2024). A&A, 682, A22. Updated plotting code to use KDE plots as requested by the referee.
