9123074 York The Digital Sky Survey is designed to produce a detailed digital photometric map of half the northern sky to about 23rd magnitude. This map will be used to select about a million galaxies and 100,000 quasars for which high-resolution spectra will be obtained with the same wide-field special purpose telescope. The imaging survey will also be used to produce a catalog in four colors of all the detected objects, about 108 galaxies and a similar number of stars, and a million quasar candidates. The survey telescope will take about four years to build and test; the survey would then be completed over a five-year period. This award supports the final design of the telescopes. ***

9123074约克 数字巡天的目的是制作一张详细的数字测光图，显示北方半个天空到大约23等。 这张地图将用于选择大约100万个星系和10万个类星体，这些星系和类星体的高分辨率光谱将由同一个宽视场专用望远镜获得。 成像调查还将用于产生所有探测到的物体的四种颜色的目录，大约108个星系和类似数量的恒星，以及100万个类星体候选者。 巡天望远镜的建造和测试将需要大约四年的时间;巡天将在五年内完成。 该奖项支持望远镜的最终设计。 ***
