The Deep Lens Survey

AST-0307714泰森深透镜调查（DLS）是一个深多波段成像调查的七个，四平方度的领域，所有数据公开。 主要的科学驱动力是弱引力透镜，但该调查也使其他调查成为可能，例如光学瞬态现象，其存在在观察后约一小时内公布。 它允许定义质量选择的星系团和三维的质量浓度，宇宙剪切和星系团计数的最终组合将对宇宙学参数施加严格的限制，并与其他探测器互补。 DLS是第一个发布图像和校准光度表的NOAO调查，完成了70%，到目前为止主要是私人资助的。 这项具体的公共支持是为了让没有资金支持的团队成员完成调查并发布最终产品，建立在迄今为止的进展基础上。为DLS开发的算法具有更广泛的适用性，发布的数据产品已经在包括高中和博物馆在内的多个级别的正规和非正规教育中使用。 DLS也是大型综合巡天望远镜的一个有用的学习工具，这是十年巡天报告中的一个优先事项，总结了天文学界对优先事项的共识。

AST-0307714TysonThe Deep Lens Survey (DLS) is a deep multi-band imaging survey of seven, four-square-degree fields, with all data made public. The primary scientific driver is weak gravitational lensing, but the survey also enables other investigations, such as optical transient phenomena, whose existence is publicized within about an hour of the observation. It allows the definition of mass-selected clusters of galaxies and of mass concentrations in three dimensions, and the final combination of cosmic shear and cluster counting will place sharp limits on cosmological parameters, and is complementary to other probes. The DLS is the first NOAO Survey to release both images and calibrated photometric catalogs, is 70% complete, and so far has been largely privately funded. This specific public support is for otherwise un-funded team members to complete the Survey and release the final products, building on the progress so far.Algorithms developed for the DLS have wider applicability, and the released data products are already in use for both formal and informal education at several levels, including high schools and museums. The DLS is also a useful learning tool for the Large Synoptic Survey Telescope, a priority in the decadal survey report summarizing the astronomical community's consensus of priorities.***
