OPTX计划I：CLANS、CLASXS和CDF-N场的通量和红移星表
The OPTX Project I: The Flux and Redshift Catalogs for the CLANS, CLASXS, and CDF-N fields
摘要：
我们提出了在钱德拉深场北（CDF-N），钱德拉大面积天气X射线巡天（CLASXS），和钱德拉洛克曼地区北巡天（CLANS）检测到的X射线源的红移目录。CDF-N和CLASXS场的星表包含了以前工作的红移，而CLANS场的红移都是新的。对于大于10^-14尔格·cm^-2·s^-1（2-8 keV）的通量，我们得到了76%的源的红移。我们扩展的红移信息的全部样本使用光度红移。OPTX项目的目标是使用这三个调查，这是迄今为止最完整的光谱调查，分析光谱类型对X射线光度函数的形状和演变的影响，并比较光谱类型与X射线光谱特性。我们还介绍了CLANS X射线目录。9个ACIS-I场覆盖的立体角约为0.6平方度，通量分别为7 x10 ^-16 ergs cm^-2 s^-1（0.5-2 keV）和3.5x10^-15 ergs cm^-2 s^-1（2-8 keV）。我们总共发现了761个X射线点源。此外，我们提出了CLANS X射线源的光学和红外光度计目录，以及CLASXS和CDF-N字段中X射线源的更新的光学和红外光度计目录。CLANS和CLASXS勘测填补了超深波束勘测（如CDF）和较浅的超大面积勘测之间的空白。因此，他们探测的X射线源，贡献了大部分的2-8 keV的X射线背景，并涵盖了所观察到的突破logN-logS分布的通量范围。我们为每个单独的字段和整个样本构建差分计数。
英文摘要：
We present the redshift catalogs for the X-ray sources detected in the Chandra Deep Field North (CDF-N), the Chandra Large Area Synoptic X-ray Survey (CLASXS), and the Chandra Lockman Area North Survey (CLANS). The catalogs for the CDF-N and CLASXS fields include redshifts from previous work, while the redshifts for the CLANS field are all new. For fluxes above 10^-14 ergs cm^-2 s^-1 (2-8 keV) we have redshifts for 76% of the sources. We extend the redshift information for the full sample using photometric redshifts. The goal of the OPTX Project is to use these three surveys, which are among the most spectroscopically complete surveys to date, to analyze the effect of spectral type on the shape and evolution of the X-ray luminosity functions and to compare the optical spectral types with the X-ray spectral properties. We also present the CLANS X-ray catalog. The nine ACIS-I fields cover a solid angle of ~0.6 square degrees and reach fluxes of 7x10^-16 ergs cm^-2 s^-1 (0.5-2 keV) and 3.5x10^-15 ergs cm^-2 s^-1 (2-8 keV). We find a total of 761 X-ray point sources. Additionally, we present the optical and infrared photometric catalog for the CLANS X-ray sources, as well as updated optical and infrared photometric catalogs for the X-ray sources in the CLASXS and CDF-N fields. The CLANS and CLASXS surveys bridge the gap between the ultradeep pencil-beam surveys, such as the CDFs, and the shallower, very large-area surveys. As a result, they probe the X-ray sources that contribute the bulk of the 2-8 keV X-ray background and cover the flux range of the observed break in the logN-logS distribution. We construct differential number counts for each individual field and for the full sample.
