摘要
扼要介绍了施密特巡天底片及基于此编制而成的施密特巡天星表的发展历程,并详细介绍了GSC2.3和USNO-B1.0的情况.分析研究了这类星表存在的问题和原因所在,并提出了一个新的计划:利用现有施密特底片资料并增加新的第3期观测,编制一个具有绝对自行、多色测光、系统均匀的高密度全天星表以满足各方面的需要.
Schmidt sky surveys, GSC and USNO Catalogues which are derived from the Schmidt sky surveys are reviewed. Systemic errors of these two catalogues both in positions and proper motions are found. The problems in these kinds of catalogues are analyzed. At the same time, a proposal for compiling a new Schmidt sky survey catalogue is also presented： Implementing a new all sky CCD survey to get the recent third epoch data. Combining the existing Schmidt sky survey data and the new data to get an all sky catalogue, this contains high precision positions, absolute proper motions, multi-band photometries, classifications and a uniform system. The positional accuracy and proper motion errors of the new catalog will be better than 0.1 arcsec and 3 mas/a accordingly.
