Standard Star Optical CCD Photometry

电话：95-28177 兰道特博士将完成一项关于光度标准星星序列的长期工作。 这项工作的目标是建立接近天球赤道21等的UBVRI序列，建立+45度赤纬带的UBVRI序列，改进一些以前观察到的序列，比较一些+45度序列的CCD照片和光电数据，并在时间和资源允许的情况下监测和减少二级项目对象的结果。 ***

Landolt, Arlo 95-28177 Dr. Landolt will complete a career long work on photometric standard star sequences. The goals of this effort are to establish UBVRI sequences approaching the 21st magnitude at the celestial equator, to establish UBVRI sequences at the +45 deg declination zone, to refine some previously observed sequences, to compare the CCDphot and photoelectric data for some of the +45 deg sequences, and to monitor and reduce the results for the secondary program objects as time and resources permit. ***
