Standard Star Optical CCD Photometry

Landolt博士将完成他在光度标准恒星序列方面的长期工作。本研究的目标是在天球赤道建立接近21等的UBVRI序列，在+45°赤纬区建立UBVRI序列，对部分观测序列进行细化，对部分+45°序列进行CCDphot和光电数据的比较，并在时间和资源允许的情况下对次级程序对象进行监测和减少结果。＊＊＊

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. ***
