Replication package for: Statistical evidence for systematic changes in solar activity during and following 90° planetary configuration intervals

This archive contains the full replication package for the manuscript “Statistical evidence for systematic changes in solar activity during and following 90° planetary configuration intervals” submitted to Earth, Planets and Space (Express Letter). The package includes:• Configuration interval definitions based on fixed planetary vector weights• Python scripts used to generate Figure 1 and Figure 2• Statistical routines for variance ratio testing and post-event level analysis• Sensitivity tests for smoothing window definitions• Instructions for reproducing all reported numerical results All planetary weights and angular criteria are pre-specified and not estimated from the sunspot data. The sunspot data used in the analysis (International Sunspot Number Version 2) are publicly available from the Solar Influences Data Analysis Center (SIDC). Planetary ephemeris data are publicly available from NASA JPL Horizons.
