Technical Support for the New Palomar Sky Survey

加州理工学院的科学家们正在 进行一项新的帕洛玛天文台巡天计划， 二. 三笔私人赠款资助了望远镜的升级 和实验室设施。 美国国家科学基金会 基金支持一位摄影科学家， 控制必要的生产高品质的集合 照相底片。 帕洛玛天文台的第一次巡天， 1952年至1957年期间，是一个非常重要的参考来源 所有的天文学。 然而，由于天空不断地 通过长期的光谱和强度变化而改变， 天体的自行，以及相对较短的时间 爆炸性事件，以及通过改进仪器 和摄影技术，重复了30年前的地图集， 非常重要。

Scientists at the California Institute of Technology are carrying out a new Palomar Observatory Sky Survey known as POSS II. Three private grants funded an upgrading of the telescope and laboratory facilities. National Science Foundation (NSF) funds support a photographic scientist who oversees the quality control necessary to produce a collection of high quality photographic plates. The first Palomar Observatory Sky Survey, produced in the period 1952-1957, is an extremely important reference source for all of astronomy. However, since the sky is constantly changing through long term spectral and intensity changes, proper motions of celestial objects, and relatively short term explosive events, as well as through improved instrumentation and photographic techniques, a repeat of the 30 year old atlas is of great importance.
