LAMOST试验性测量的LEGUE高纬度明亮测量设计
The LEGUE High Latitude Bright Survey Design for the LAMOST Pilot Survey
摘要：
我们描述的足迹和输入目录明亮的夜晚在LAMOST试点调查，这开始于2011年10月。目标是从南北银帽区的两个条纹中选择的，中心在$α$ = 29 $^\circ$，10度角宽，覆盖赤经分别为135 $^\circ-290^\circ$和-30 $^\circ$到30 $^\circ$。我们从SDSS和2 MASS点源目录的组合中选择光谱目标。定义视场中心的星表（根据位于LAMOST视场中心的Shack-Hartmann波前传感器的要求）包括依巴谷星表中所有V <8 m的恒星。我们采用了一种统计选择算法，根据它们在多维颜色/幅度空间中的位置分配优先级的目标。该方案过分强调稀有物体，并不强调数量和颜色相位空间的更多填充区域，同时确保平滑，易于理解的选择功能。演示板设计的Shack-Hartmann星表和输入目录，这是由我们的目标选择例程的基础上。
英文摘要：
We describe the footprint and input catalog for bright nights in the LAMOST Pilot Survey, which began in October 2011. Targets are selected from two stripes in the north and south Galactic Cap regions, centered at $α$= 29$^\circ$, with 10$^\circ$ width in declination, covering right ascension of 135$^\circ-290^\circ$ and -30$^\circ$ to 30$^\circ$ respectively. We selected spectroscopic targets from a combination of the SDSS and 2MASS point source catalogs. The catalog of stars defining the field centers (as required by the Shack-Hartmann wavefront sensor at the center of the LAMOST field) consists of all V < 8m stars from the Hipparcos catalog. We employ a statistical selection algorithm that assigns priorities to targets based on their positions in multidimensional color/magnitude space. This scheme overemphasizes rare objects and de-emphasizes more populated regions of magnitude and color phase space, while ensuring a smooth, well-understood selection function. A demonstration of plate design is presented based on the Shack-Hartmann star catalog and an input catalog that was generated by our target selection routines.
