SWIRE 红移数据

We have revised the Spitzer Wide-Area Infrared Extragalactic survey (SWIRE) Photometric Redshift Catalogue to take account of new optical photometry in several of the SWIRE areas, and incorporating Two Micron All Sky Survey (2MASS) and UKIRT Infrared Deep Sky Survey (UKIDSS) near-infrared data. Aperture matching is an important issue for combining near-infrared and optical data, and we have explored a number of methods of doing this.我们对斯皮策广域红外河外巡天（Spitzer Wide-Area Infrared Extragalactic Survey, SWIRE）测光红移星表进行了修订，以纳入多个SWIRE天区的最新光学测光数据，并结合了两微米全天巡天（Two Micron All Sky Survey, 2MASS）与英国红外望远镜红外深巡天（UKIRT Infrared Deep Sky Survey, UKIDSS）的近红外数据。孔径匹配是结合近红外与光学数据的关键问题，我们就此探索了多种可行的处理方法。

背景概述

SWIRE 红移数据是一个天文学数据集，专注于对斯皮策广域红外河外巡天（SWIRE）测光红移星表的修订，结合了新光学测光数据、2MASS和UKIDSS近红外数据，以改进红移计算和孔径匹配方法。该数据集覆盖全天区域，包括Lockman、EN1等多个巡天区域，包含超过100万行数据，用于星系研究和红外巡天分析，由中国科学院国家天文台贡献，适用于实测天体物理学领域。
