WISE Preliminary Release Catalogs

The WISE Preliminary Release includes data from the first 105 days of WISE survey observations, 14 January 2010 to 29 April 2010, that were processed with initial calibrations and reduction algorithms. Primary release data products include an Atlas of 10,464 calibrated, coadded Image Sets, a Source Catalog containing positional and photometric information for over 257 million objects detected on the WISE images, and an Explanatory Supplement that provides a user's guide to the WISE mission and format, content, characteristics and cautionary notes for the Release products. Ancillary release products include an archive of over 754,000 Single-exposure Image sets and database of over 2.2 billion source extractions from those images, and moving object tracklets identified as part of the NEOWISE program (Mainzer et al. 2011). 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.

WISE初步发布版包含2010年1月14日至2010年4月29日期间（即WISE巡天观测的前105天）的数据，这些数据经过初始校准与归约算法处理。主要发布数据产品包括：由10464个校准叠加图像集（Image Sets）组成的图集（Atlas）、涵盖WISE图像中检测到的超2.57亿个天体位置与光度信息的源目录（Source Catalog），以及一份解释性补编（Explanatory Supplement）——该补编不仅提供WISE任务的用户指南，还详述本发布产品的格式、内容、特征及注意事项。辅助发布产品包括：超75.4万个单曝光图像集（Single-exposure Image sets）的存档、从上述图像中提取的超22亿个源的数据库，以及作为NEOWISE项目（Mainzer等人，2011）一部分识别出的移动天体轨迹段（tracklets）。该数据集或服务由IPAC的红外科学档案库（Infrared Science Archive，IRSA）提供，IPAC由加州理工学院（California Institute of Technology）根据与美国国家航空航天局（National Aeronautics and Space Administration）签订的合同运营。
