We have compiled an extensive catalog of candidate wide binaries selected from Gaia DR2 in the solar neighborhood with distances $d<4$~kpc, following a procedure similar to that of El-Badry & Rix(2018). This initial candidate catalog consists of 807,611 possible binaries. Its contamination rates are lower than 10% at $a<20,000$~AU; however, the contamination rates quickly increase beyond 20,000~AU, until up to 100% at the largest separation bin, i.e., a = 1.0 pc. To address this, we subsequently applied additional selection criteria, tailored towards three kinematically-selected, presumably pure subsamples: 4361 disk-like, 10090 intermediate, and 4351 halo-like binaries.
