UV-supported white dwarf–main sequence binary candidates at 100–300 pc (Gaia DR3)

Machine-readable tables for the discovery of white dwarf–main sequence (WDMS) binary candidates in the solar neighborhood (100–300 pc) using Gaia DR3 and GALEX ultraviolet photometry. Contains two tables: (1) goldtier.dat that includes 22 gold-tier WDMS candidates selected by a gradient-boosting classifier (P > 0.8) with GALEX NUV excess < −1.5 mag, including Gaia DR3 photometry, classifier probabilities, CMD offsets, and NUV excess values; (2) wdmssupp.dat that includes 368-row supplement of all new photometric candidates, including silver-tier systems, candidates awaiting UV follow-up, and galaxy-neighbour flags. Training labels from Rebassa-Mansergas et al. (2025, A&A 699, A153). All coordinates ICRS J2016.0. Fixed-width ASCII format with ReadMe documentation following CDS conventions.
