本文介绍了利用MIPSGAL 24 μm银道巡天的影像数据和相应的数据产品建立24 μm点源星表的方法。高质量的目录产品包含933，818个来源，在完整的存档目录中共有1，353，228个。源表包括来自24 μm图像的位置和光度信息、源质量和混淆标志以及来自匹配的2MASS、GLIMPSE和WISE点源的对应光度信息。完整性衰减数据立方体以1′角分辨率构造，描述了MIPSGAL场上变化的背景水平以及从该背景中提取给定震级源的能力。完整性衰减立方体被包括在数据产品的集合中。我们提出了我们的努力，以验证天体测量和测光校准的目录的结果，并提出了一些分析这些测量中的微小异常，以证明所采取的缓解策略。
In this contribution, we describe the applied methods to construct a 24 μm based point source catalog derived from the image data of the MIPSGAL 24 μm Galactic Plane Survey and the corresponding data products. The high quality catalog product contains 933,818 sources, with a total of 1,353,228 in the full archive catalog. The source tables include positional and photometric information derived from the 24 μm images, source quality and confusion flags, and counterpart photometry from matched 2MASS, GLIMPSE, and WISE point sources. Completeness decay data cubes are constructed at 1′ angular resolution that describe the varying background levels over the MIPSGAL field and the ability to extract sources of a given magnitude from this background. The completeness decay cubes are included in the set of data products. We present the results of our efforts to verify the astrometric and photometric calibration of the catalog, and present several analyses of minor anomalies in these measurements to justify adopted mitigation strategies.
