  Almost every star in our Galaxy is likely to harbor a terrestrial planet, but
accurate measurements of an exoplanet's mass and radius demands accurate
knowledge of the properties of its host star. The imminent TESS and CHEOPS
missions are slated to discover thousands of new exoplanets. Along with WFIRST,
which will directly image nearby planets, these surveys make urgent the need to
better characterize stars in the nearby solar neighborhood (< 30 pc). We have
compiled the CATalog of Stellar Unified Properties (CATSUP) for 951 stars,
including such data as: Gaia astrometry; multiplicity within stellar systems;
stellar elemental abundance measurements; standardized spectral types; Ca II H
and K stellar activity indices; GALEX NUV and FUV photometry; and X-ray fluxes
and luminosities from ROSAT, XMM, and Chandra. We use this data-rich catalog to
find correlations, especially between stellar emission indices, colors, and
galactic velocity. Additionally, we demonstrate that thick-disk stars in the
sample are generally older, have lower activity, and have higher velocities
normal to the galactic plane. We anticipate CATSUP will be useful in discerning
other trends among stars within the nearby solar neighborhood, for comparing
thin-disk vs. thick-disk stars, for comparing stars with and without planets,
and for finding correlations between chemical and kinematic properties.
