SkyMapper和南天巡天--南天的资源

SkyMapper and the Southern Sky Survey - a resource for the southern sky

S. C. Keller, B. P. Schmidt, M. S Bessell

摘要:

SkyMapper是新一代专用宽视场巡天望远镜中的第一批。1.3米长的SkyMapper望远镜拥有5.7平方度的视场卡塞格伦成像仪,将于2007年底看到第一束光。该设施的主要目标是进行南方天空调查,对南方天空进行六色六历元调查。这次巡天将为8至23等的天体提供光度测量,全球光度测量精度为0.03等,天体测量精度为50等。这将是南部天空的宝贵科学资源,此外还为成像数据的光度和天体测量校准提供了基础。

英文摘要:

SkyMapper is amongst the first of a new generation of dedicated, wide-field survey telescopes. The 1.3m SkyMapper telescope features a 5.7 square degree field-of-view Cassegrain imager and will see first light in late 2007. The primary goal of the facility is to conduct the Southern Sky Survey a six colour, six epoch survey of the southern sky. The survey will provide photometry for objects between 8th and 23rd magnitude with global photometric accuracy of 0.03 magnitudes and astrometry to 50 mas. This will represent a valuable scientific resource for the southern sky and in addition provide a basis for photometric and astrometric calibration of imaging data.
