A Uniform Stacked-ISW Analysis of Voids from DESI, BOSS, and SDSS (data and code release)

This archive contains the analysis code, stacked CMB temperature profiles, derived tables, and publication figures accompanying the paper “A Uniform Stacked-ISW Analysis of Voids from DESI, BOSS, and SDSS” (submitted). The code implements a uniform pipeline for stacking Planck 2018 SMICA CMB data around voids and superclusters from DESI, BOSS DR12, and SDSS DR7. The data products include random-subtracted annular and compensated-aperture profiles, ring–core ISW contrasts, and the figures used in the manuscript. No proprietary or third-party survey data are redistributed here. For raw catalogues and masks, users should refer to the original DESI, BOSS, SDSS, and Planck data releases as listed in data_sources.txt.
