cds-question@unistra.frasteroidsinfrared-photometrysurveysWe present preliminary diameters and albedos for 7956 asteroids detected in the first year of the NEOWISE Reactivation mission. Of those, 201 are near-Earth asteroids and 7755 are Main Belt or Mars-crossing asteroids. 17% of these objects have not been previously characterized using the Near-Earth Object Wide-field Infrared Survey Explorer, or "NEOWISE" thermal measurements. Diameters are determined to an accuracy of ~20% or better. If good-quality H magnitudes are available, albedos can be determined to within ~40% or better.2015ApJ...814..117Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/814/117CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/astorb : Orbits of Minor Planets (Bowell+ 2014)II/190 : IRAS Minor Planet Survey (IMPS) (Tedesco 1992)VII/108 : Asteroids II Machine-Readable Data Base (Binzel+ 1987)VII/91 : IRAS Asteroid and Comet Survey (Veeder+ 1986)J/MNRAS/433/2075 : Asteroid families identification (Carruba+, 2013)J/ApJ/770/7 : WISE/NEOWISE Main Belt asteroids (Masiero+, 2013)J/ApJ/760/L12 : WISE/NEOWISE NEOs preliminary thermal fits (Mainzer+, 2012)J/ApJ/759/L8 : WISE/NEOWISE obs. of main belt asteroids (Masiero+, 2012)J/ApJ/759/49 : Jovian Trojan asteroids with WISE/NEOWISE (Grav+, 2012)J/ApJ/744/197 : WISE/NEOWISE observations of Hilda asteroids (Grav+, 2012)J/ApJ/743/156 : NEOWISE obs. of NEOs: preliminary results (Mainzer+, 2011)J/ApJ/742/40 : Jovian Trojans asteroids with WISE/NEOWISE (Grav+, 2011)J/ApJ/741/68 : Main Belt asteroids with WISE/NEOWISE.
