VizieR Online Data Catalog: NEWS catalog (Khramtsov+, 2020)
Abstract
The released NEWS catalog includes PS1xAllWISE sources up to g=23mag, excluding the sources with optical magnitude errors higher than 0.5mag (in any of five bands) and with a low mid-IR SNR (w1snr<5, w2snr<2). These sources were classified as extragalactic objects via machine learning algorithm. In this catalog we present the sources, for which classification probability of being extragalactic is more than 0.5.
