AI 中文摘要
我介绍了Spitzer数据融合,这是一个多波段测光数据库,为八个最广泛研究的河外星系巡天场中65平方度范围内的440万个IRAC选源提供了远紫外至远红外的通量测量,以及测光和光谱红移。一个配套产品,SERVS数据融合,提供了从更深的斯皮策热任务成像中选出的18平方度范围内的280万个源。星表使用与波长相关的匹配半径进行波段合并,针对2MASS进行天体测量配准,并以FITS二进制表的形式分发,每个场一个表,同时以DOI: https://doi.org/10.5281/zenodo.6120913和CDS/VizieR星表II/377的形式提供。该数据库旨在作为社区资源,用于测光红移校准、光谱能量分布拟合、样本选择和多波段交叉识别,并且是斯皮策传统场与正在进行的Euclid、Rubin和SKA前驱巡天之间的自然桥梁。
英文摘要
I present the Spitzer Data Fusion, a multi-wavelength photometric database providing far-ultraviolet to far-infrared flux measurements, together with photometric and spectroscopic redshifts, for 4.4 million IRAC-selected sources over 65\,deg$^2$ in eight of the most widely studied extragalactic survey fields. A companion product, the SERVS Data Fusion, provides 2.8 million sources over 18\,deg$^2$ selected from deeper Spitzer warm-mission imaging. Catalogs are band-merged with wavelength-dependent matching radii, astrometrically registered against 2MASS, and distributed as FITS binary tables, one per field, as \href{https://doi.org/10.5281/zenodo.6120913}{DOI: 10.5281/zenodo.6120913} and as CDS/VizieR \href{https://cdsarc.cds.unistra.fr/viz-bin/cat/II/377}{catalog II/377}. The database is intended as a community resource for photometric redshift calibration, spectral energy distribution fitting, sample selection and multi-wavelength cross-identification, and is a natural bridge between the Spitzer legacy fields and ongoing Euclid, Rubin and SKA precursor surveys.
