VIDEO - VISTA Deep Extragalactic Observations Survey

VIDEO is a deep near-­infrared survey which targets ~12 square degrees over the ELAIS-­‐S1, XMMLSS, and ECDFS extragalactic fields. We recommend using only those sources with Ks<23.5 for most studies as this gives a completeness of ~90 per cent (Jarvis et al. 2013, MNRAS, 428, 1281).VIDEO是一项深近红外巡天项目，其观测覆盖ELAIS-S1、XMMLSS与ECDFS三个河外天区，总面积约12平方度。我们建议绝大多数研究仅选用Ks星等小于23.5的天体源，此时的源探测完备率约为90%（Jarvis等，2013，《皇家天文学会月报》，428卷，1281页）。
