NEOWISE 2-Band Post-Cryo Single Exposure (L1b) Known Solar System Object Possible Association List

The NEOWISE Post-Cryo Data Release products were generated using data taken during the mission's Post-Cryo survey phase. This phase covers the time following the exhaustion of solid hydrogen in the WISE payload inner cryogen tank, when the detectors and optics gradually warmed until they reached a stable equilibrium temperature near 73.5 K. During this time, WISE's W1 and W2 detectors continued to acquire high quality imaging data with sensitivities close to that during the mission's cryogenic survey phases. The W3 and W4 detectors were fully saturated by the thermal emission from the warming telescope. WISE scanned approximately 70% of the sky during the Post-Cryo survey phase continuing with the same strategy that was used during the full cryogenic survey. 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.

NEOWISE后低温阶段数据发布产品基于该任务后低温巡天阶段采集的数据生成。该阶段涵盖WISE有效载荷内部低温储罐中固态氢耗尽后的时期，在此期间探测器与光学系统逐渐升温，直至达到约73.5 K的稳定平衡温度。在此期间，WISE的W1与W2探测器持续获取高质量成像数据，其灵敏度接近任务低温巡天阶段的水平；而W3与W4探测器则因望远镜升温产生的热辐射而完全饱和。NEOWISE在后低温巡天阶段沿用了全低温巡天期间的观测策略，扫描了约70%的天区。已知太阳系天体可能关联列表是一份小行星与彗星的汇编，涵盖WISE二次数据处理时已确知轨道、且预测会出现在单帧WISE曝光视场内的天体。由于单个天体被多次观测，列表中可能存在多条记录；当太阳系天体的预测位置与WISE单帧曝光中的探测源接近时，还会提供WISE源的位置与亮度信息。本数据集或服务由IPAC的红外科学档案库（IRSA）提供，该档案库由加州理工学院根据与美国国家航空航天局的合同运营。
