WISE 3-Band Cryo Known Solar System Object Possible Association List

The WISE 3-Band Cryo Single Exposure (L1b) Source Table contains positions and photometry in the 3.4, 4.6 and 12 μm bands for 3,703,319,374 sources extracted from observations made during the WISE 3-Band Cryo survey phase, 6 August 2010 through 29 September 2010. WISE scanned approximately 30% of the sky during this period when the telescope and focal planes operated at a slightly higher temperature, but were still cooled by solid hydrogen in the inner cryogen tank. The Known Solar System Object Possible Associations List is a compendium of asteroids and comets, with orbits known at the time of WISE second-pass data processing, that were predicted to be within the field-of-view at the time of individual WISE exposures. Individual objects were observed multiple times, so may have multiple entries in the list. When the predicted position of a solar system object is in proximity to a detection in the WISE single-exposures, the WISE source position and brightness information are also provided. This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.

广域红外巡天探测器（Wide-field Infrared Survey Explorer, WISE）三波段低温单次曝光（L1b）源表收录了2010年8月6日至2010年9月29日WISE三波段低温巡天阶段获取的观测数据中提取的3703319374个天体源的3.4μm、4.6μm及12μm波段的位置与测光信息。在此巡天期间，望远镜与焦平面虽工作温度略高于标准低温工况，但仍依靠内部低温储罐内的固态氢实现冷却，WISE完成了约30%天区的扫描观测。太阳系已知天体潜在关联列表汇编了小行星与彗星，其轨道参数取自WISE二次数据处理阶段时已测定的公开数据，这些天体被预测在单次WISE曝光时处于探测器视场范围内。单个太阳系天体可被多次观测，因此在该列表中可能存在多条对应记录。当某一太阳系天体的预测位置与WISE单次曝光中的探测源位置相近时，同步提供该WISE源的位置与亮度信息。本数据集及服务由受美国国家航空航天局（National Aeronautics and Space Administration, NASA）委托、加州理工学院运营的红外处理与分析中心（Infrared Processing and Analysis Center, IPAC）下属红外科学档案馆（Infrared Science Archive, IRSA）发布。
