Multiwavelength Catalog of 10,000 4XMM-DR13 Sources with Known Classifications

We present a collection of $\sim 10,000$ X-ray sources from the 4th XMM-Newton Serendipitous Source Catalog (4XMM-DR13) with literature-verified classifications and multi-wavelength (MW) counterparts. We describe the process by which MW properties are obtained and an interactive online visualization tool we developed.
