Discovery and Characterization of White Dwarf--FGK Main-Sequence Binary Candidates within the Optical Main-Sequence Locus

This dataset contains the catalogs accompanying the paper “Discovery and Characterization of White Dwarf–FGK Main-Sequence Binary Candidates within the Optical Main-Sequence Locus”, to be submitted to The Astrophysical Journal Supplement Series (ApJS) in December 2025. Two data files are included: 1. wdms772_UV_excess.csvThis file lists the 772 WDMS candidates identified through ultraviolet-excess selection. It provides the basic source information together with the prior values adopted for the subsequent binary SED fitting. 2. wdms759_precision.csvThis file contains the 759 WDMS candidates with well-constrained binary SED fits. For each system, we provide the fitted parameters of both stellar components, as well as the stellar masses and ages inferred through interpolation of evolutionary models. These catalogs form the basis of the WDMS candidate sample presented and analyzed in the accompanying paper.
