VizieR Online Data Catalog: Thermal model fits for short-arc NEOs with NEOWISE (Masiero+, 2018)

We used the Solar System Object search tool provided by the NASA/IPAC Infrared Science Archive (IRSA) in the WISE image server (http://irsa.ipac.caltech.edu/applications/wise/) to determine the predicted locations for all NEOs with provisional designations assigned from the start of 2014 to the end of 2016 for which detections had not already been reported by NEOWISE. This tool uses the spacecraft position as well as the propagated orbit of the asteroid from JPL Horizons (http://ssd.jpl.nasa.gov/horizons.cgi) to determine if the object was coincident with any recorded NEOWISE image at the time that image was acquired. Our search included both bands acquired by the NEOWISE survey: 3.4 μm (W1) and 4.6 μm (W2). For objects detected in both bands, we require that the object has an NEO-like color (i.e., W1-W2>1 mag, as opposed to stars that usually have a color of W1-W2~0). We detect 33 asteroids in a single NEOWISE exposure set and 89 in multiple exposures, for a total of 354 visually confirmed detections of 122 NEOs. We use the Near-Earth Asteroid Thermal Model (NEATM, Harris 1998Icar..131..291H) to determine the physical properties of the observed NEOs, following the process and selection criteria described in our previous work (e.g., Nugent et al. 2015, J/ApJ/814/117; 2016, J/AJ/152/63; Masiero et al. 2017, J/AJ/154/168).
