Abstract AST-9419906 Helfand, David J. Collaborative Project: The FIRST Survey: Faint Images of the Radio Sky at Twenty-cm. Dr. Robert Becker, at the University of California at Davis, and Dr. David Helfand, at Columbia University, will collaborate on a project to carry out a survey known as FIRST Survey: Faint Images of the Radio Sky at Twenty-cm. The survey will be done with the Very Large Array (VLA) of the National Radio Astronomy Observatory at a wavelength of twenty centimeters. A catalog of over one million radio sources, each with position accurate enough to allow unambiguous identification of their optical counterparts, will be derived from the data. FIRST will provide a fundamental resource for the world-wide astronomical community. ***

David J. Helfand， AST-9419906合作项目：第一次调查：20厘米处射电天空的微弱图像。加州大学戴维斯分校的罗伯特·贝克尔博士和哥伦比亚大学的大卫·赫尔芬博士将合作开展一项名为“第一调查”的调查项目：20厘米处射电天空的微弱图像。此次巡天将由国家射电天文台的甚大阵列（VLA）进行，波长为20厘米。将从这些数据中得出一个超过100万个射电源的目录，每个射电源的位置都足够精确，可以明确地识别它们的光学对应物。FIRST将为全球天文学界提供一个基础资源。＊＊＊
