The XMM-RM project was designed to provide X-ray coverage of the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) field. Forty-one XMM-Newton exposures, placed surrounding the Chandra AEGIS field, were taken, covering an area of 6.13 deg 2 and reaching a nominal exposure depth of ∼15 ks. We present an X-ray catalog of 3553 sources detected in these data, using a PSF-fitting algorithm and a sample selection threshold that produces a ∼5% fraction of spurious sources. In addition to the PSF-fitting likelihood, we calculate a second source reliability measure based on Poisson theory using source and background counts within an aperture. Using the Poissonian likelihood, we select a subsample with a high purity and find that it has number count profiles similar to previous X-ray surveys. The Bayesian method “NWAY” was employed to identify counterparts of the X-ray sources from the optical Legacy and the IR unWISE catalogs, using a two-dimensional unWISE magnitude–col...

Sloan数字天空测量混响映射项目：XMM-Newton X射线源目录和多频段对应产品

XMM-RM项目旨在提供Sloan数字天空测量混响图（SDSS-RM）字段的X射线覆盖范围。围绕钱德拉AEGIS场进行了41次XMM-牛顿曝光，覆盖面积为6.13度2，名义曝光深度约为15 ks。我们使用PSF拟合算法和产生约5％杂散源的样本选择阈值，提供了在这些数据中检测到的3553个源的X射线目录。除了PSF拟合的可能性外，我们还基于Poisson理论使用光圈内的源和背景计数来计算第二个源可靠性度量。使用泊松似然法，我们选择了一个高纯度的子样本，并发现它具有与以前的X射线调查相似的数量计数轮廓。
