我们描述了一项利用MOPRA 22米射电望远镜进行的试点调查，为90 GHz毫米波天文遗产团队调查(MALT90)做准备。我们使用六种不同的选择标准识别了182个候选致密分子簇，并将每个源同时映射到接近90 GHz的16条不同的线上。我们总结了这些数据，并描述了试点调查的结果如何影响了更大规模的MALT90调查的设计。我们根据试点探测率激励我们为主要调查选择目标源，并展示在高光谱分辨率下同时绘制多条线的价值。
We describe a pilot survey conducted with the Mopra 22 m radio telescope in preparation for the Millimeter Astronomy Legacy Team Survey at 90 GHz (MALT90). We identified 182 candidate dense molecular clumps using six different selection criteria and mapped each source simultaneously in 16 different lines near 90 GHz. We present a summary of the data and describe how the results of the pilot survey shaped the design of the larger MALT90 survey. We motivate our selection of target sources for the main survey based on the pilot detection rates and demonstrate the value of mapping in multiple lines simultaneously at high spectral resolution.
