LAMOST试点调查中用于暗夜观测的LEGUE输入目录
The LEGUE Input Catalogue for Dark Night Observing in the LAMOST Pilot Survey
摘要：
我们概述了LAMOST试点调查的黑夜部分的设计，该调查于2011年10月开始观测。特别是，我们专注于银河系恒星候选人，有针对性的LEGUE（LAMOST实验银河系的理解和探索）调查。我们讨论了光谱候选人被选中的天空区域，以及选择这些天空区域的动机。由于望远镜的独特设计的一些限制进行了讨论，包括一个明亮的（V < 8）的恒星被放置在每个板的中心的波前传感和主动光学校正的要求。简要讨论了目标选择类别和激励它们的科学目标，然后详细概述了这些选择功能是如何实现的。我们说明了整个输入目录-斯隆数字巡天（SDSS）测光-和LAMOST观测选择的最终目标之间的差异。
英文摘要：
We outline the design of the dark nights portion of the LAMOST Pilot Survey, which began observations in October 2011. In particular, we focus on Milky Way stellar candidates that are targeted for the LEGUE (LAMOST Experiment for Galactic Understanding and Exploration) survey. We discuss the regions of sky in which spectroscopic candidates were selected, and the motivations for selecting each of these sky areas. Some limitations due to the unique design of the telescope are discussed, including the requirement that a bright (V < 8) star be placed at the center of each plate for wavefront sensing and active optics corrections. The target selection categories and scientific goals motivating them are briefly discussed, followed by a detailed overview of how these selection functions were realized. We illustrate the difference between the overall input catalog - Sloan Digital Sky Survey (SDSS) photometry - and the final targets selected for LAMOST observation.
