15.7 GHz射电源10 C调查：I -观测、绘图和源提取
10C Survey of Radio Sources at 15.7 GHz: I - Observing, mapping and source extraction
摘要：
我们使用弧分钟微开尔文成像仪大阵列，在15.7 GHz处观测到了一个均方根噪声水平小于0.2 mJy的约27 ° ^2的区域。这些观测结果构成了1.4 GHz以上任何范围（大于约0.2度^[2]）最灵敏的射电源调查。本文介绍了观测、制图和源提取所采用的技术。我们已经使用了一个系统的程序来提取信息和生产源目录，从不同的噪音和紫外线覆盖的地图。我们已经进行了模拟，以测试我们的映射和源提取程序，并制定了方法，用于识别扩展，重叠和虚假的来源，在嘈杂的图像。在AMI Consortium：Davies et al. 2010的随附论文中，介绍了10 C调查的第一批结果，包括深层15.7 GHz源计数。
英文摘要：
We have observed an area of approximatley 27 deg^2 to an rms noise level of less than 0.2 mJy at 15.7 GHz, using the Arcminute Microkelvin Imager Large Array. These observations constitute the most sensitive radio-source survey of any extent (greater than approximately 0.2 deg^2) above 1.4 GHz. This paper presents the techniques employed for observing, mapping and source extraction. We have used a systematic procedure for extracting information and producing source catalogues, from maps with varying noise and uv-coverage. We have performed simulations to test our mapping and source-extraction procedures, and developed methods for identifying extended, overlapping and spurious sources in noisy images. In an accompanying paper, AMI Consortium: Davies et al. 2010, the first results from the 10C survey, including the deep 15.7-GHz source count, are presented.
