我们提出了天蝎座领域的大量扩展射电源样本的目录，由澳大利亚望远镜紧凑型阵列观测和解决。天蝎座是一个探路者项目，用于解决澳大利亚SKA探路者的早期操作，是一个在1.4和3.1 GHz之间约5平方度的调查，中心为l = 343.5〇，b = 0.75〇，角分辨率约为10弧秒。它的目的是了解未来银河系调查将面临的科学和技术挑战。在平均灵敏度约为$100\ \mu \mathrm{Jy\ beam}^{-1}$的情况下，我们提取了99个扩展源，其中35个是首次检测到的。在64个已知的来源中，有55个在文献中至少有一个暂定的分类。通过对射电形态的研究，并将射电辐射与红外辐射进行比较，我们提出了6个新的H区、2个新的行星状星云、2个新的发光蓝色变星或沃尔夫-拉叶星和3个新的超新星遗迹作为候选区域。本研究概述了未来射电调查在银河系源提取和表征方面的潜力，并讨论了在银河系平面上减少和分析干涉数据的难度。
We present a catalogue of a large sample of extended radio sources in the SCORPIO field, observed and resolved by the Australia Telescope Compact Array. SCORPIO, a pathfinder project for addressing the early operations of the Australia SKA Pathfinder, is a survey of ∼5 square degrees between 1.4 and 3.1 GHz, centered at l = 343.5○, b = 0.75○ and with an angular resolution of about 10 arcsec. It is aimed at understanding the scientific and technical challenges to be faced by future Galactic surveys. With a mean sensitivity around $100\ \mu \mathrm{Jy\ beam}^{-1}$ and the possibility to recover angular scales at least up to 4 arcmin, we extracted 99 extended sources, 35 of them detected for the first time. Among the 64 known sources 55 had at least a tentative classification in literature. Studying the radio morphology and comparing the radio emission with infrared we propose as candidates 6 new H ii regions, 2 new planetary nebulae, 2 new luminous blue variable or Wolf–Rayet stars and 3 new supernova remnants. This study provides an overview of the potentiality of future radio surveys in terms of Galactic source extraction and characterization and a discussion on the difficulty to reduce and analyze interferometric data on the Galactic plane.
