Abstract

We discuss the technique and results of photometric measurements based on data from the WISE infrared survey for all Pan-STARRS1 objects under the assumption that the object coordinates are known (‘‘forced’’ photometry). The photometry has been performed by taking into account a complete point spread function model and a refined background model in the WISE survey. The fluxes or upper limits on the flux in the 3.4 and 4.6 \(\mu\)m bands have been measured for more than three billion optical objects in the northern sky at declinations \(\delta>{-}30^{\circ}\). These measurements will be used to identify galaxy clusters, active galactic nuclei, and quasars in the all-sky surveys of the eROSITA and Mikhail Pavlinsky ART-XC telescopes onboard the Spektr–Roentgen–Gamma space observatory.

基于WISE数据的Pan-STARRS1物体的强迫测光

我们讨论了基于WISE红外测量数据的光度测量技术和结果，这些数据来自所有Pan-STARRS1物体，假设物体坐标已知（“强制”光度测量）。在WISE调查中，通过考虑完整的点扩散函数模型和精细的背景模型进行了测光。在赤纬（δ>；{-}30^｛\circ｝\）。这些测量结果将用于在Spektr–Roentgen–Gamma太空天文台上的eROSITA和Mikhail Pavlinsky ART-XC望远镜的全天空观测中识别星系团、活动星系核和类星体。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
