THE UPCOMING NASA TESS MISSION HAS AS ITS PRIMARY SCIENCE GOAL THE DISCOVERY OF EARTH-LIKE PLANETS WHOSE PROPERTIES (INCLUDING ESPECIALLY THEIR MASSES) CAN BE MEASURED. JUST AS THE KEPLER MISSION PROVIDED A KEPLER INPUT CATALOG (KIC) THE TESS MISSION INCLUDES PLANS TO CREATE A TESS INPUT CATALOG (TIC) THAT PROVIDES CERTAIN BASIC INFORMATION ABOUT THE POTENTIAL TARGET STARS WITHIN THE TESS FIELD OF VIEW. HOWEVER THERE ARE A NUMBER OF ADDITIONAL PROPERTIES OF THE TARGET STARS THAT WHILE NOT REQUIRED FOR THE MISSION WOULD ENABLE MAXIMUM SCIENCE OUTPUT FROM TESS WITH RESPECT TO DISCOVERY AND CHARACTERIZATION OF TRANSITING PLANETS. ONE EXAMPLE IS ACCURATE AND EMPIRICAL STELLAR RADIUS DETERMINATIONS FROM WHICH TO INFER THE MOST ACCURATE PLANET RADII; ANOTHER EXAMPLE IS STELLAR ACTIVITY MEASURES WITH WHICH TO SELECT THE SYSTEMS MOST AMENABLE TO RADIAL-VELOCITY FOLLOWUP. OUR TEAM HAS BEEN DEVELOPING TECHNIQUES---INCLUDING USE OF THE GAIA DR2 PARALLAXES WHOSE DELIVERY IS EXPECTED DURING THE FIRST HALF OF 2018---TO DETERMINE A COMPREHENSIVE SUITE OF PRECISE PROPERTIES FOR THE STARS THAT WILL BE TARGETED BY TESS. THE GOAL OF THIS PROJECT IS TO DEVELOP A COMMUNITY VALUE-ADDED TIC (CVA-TIC) OF PRECISE STELLAR PROPERTIES FOR A LARGE FRACTION OF POTENTIAL TESS TARGETS THUS PROVIDING A SCIENCE-ENABLING RESOURCE TO THE BROADER TESS COMMUNITY COMPLEMENTING AND EXTENDING THAT PROVIDED BY THE MISSION. STELLAR PROPERTIES THAT WE EXPECT TO BE ABLE TO PROVIDE INCLUDE: A VARIETY OF STELLAR EFFECTIVE TEMPERATURE ESTIMATES AND NEW EMPIRICALLY DETERMINED STELLAR RADII AND MASSES FOR 100 MILLION STARS; TEMPERATURES AND RADII AND MASS ESTIMATES FOR A CAREFULLY VETTED SAMPLE OF 1 MILLION BONA FIDE M-DWARFS; ROTATION PERIODS AND OTHER ACTIVITY INDICATORS FROM LONG-TERM MONITORING SURVEYS SUCH AS OUR OWN KELT SURVEY FOR 4 MILLION STARS; AND THE COMPILATION OF NUMEROUS LARGE PHOTOMETRIC AND SPECTROSCOPIC SURVEYS SUCH AS SDSS UCAC4 APOGEE AND RAVE. FINALLY WE PROVIDE 15 OPTICAL TO NEAR IR BANDPASSES AND PROPER MOTIONS FOR MORE THAN 400 MILLION OBJECTS. THIS NEW RESOURCE -- THE CVA-TIC -- WILL COMPLEMENT ENHANCE AND EXTEND THE TIC AND WILL BE MADE AVAILABLE TO THE COMMUNITY FOR READY USE VIA OUR FILTERGRAPH DATA-VISUALIZATION PORTAL SYSTEM AS WELL AS VIA THE MAST SERVER.
