This dataset includes supplemental materials for the article, "The Intermediate Mass Black Hole in Omega Centauri: Constraints on Accretion from JWST (arXiv:2511.20945)," accepted into The Astrophysical Journal. The dataset includes: The Jupyter notebook which implements the workflow used to align JWST and oMEGACat images and sources The aligned oMEGACAT and JWST FITS images oMEGACat, NIRCam and MIRI source catalogs before alignment (ngc5139_omegacat.csv, omega_cen_jwst_nircam_phot.csv, omega_cen_jwst_miri_phot.csv) NIRCam and MIRI source catalogs after alignment (omega_cen_jwst_miri_phot_cor.csv, omega_cen_jwst_nircam_phot_cor.csv) oMEGACat source catalog crossmatched to JWST sources after alignment (ngc5139_omegacat_jwst_kargaltsev_propagated.csv) DOLPHOT parameter files for NIRCam and MIRI images
