Fundamental Optical Photometry

无论是在地面上还是在太空中建造和运行新的大型望远镜，都需要测量分布在天空中的一系列微弱恒星的亮度和颜色。在这项为期两年的研究中，作者将继续之前的工作，将两个半球的微弱“光度标准”列表扩展到10-21级范围。预计这项工作和配套工作将满足天文学的许多需要，需要观测暗淡的恒星和星系。此外，该项目还将建立一个数据库，将用光电倍增管进行的标准测光与用“电荷耦合器件”(电荷耦合器件)获得的测光进行比较。

The construction and operation of new large telescopes both on the ground and in space requires the measurement of the brightness and colors for a sequence of faint stars distributed across the sky. In this two-year study the author will continue previous work extending a list of faint "photometric standards" in both hemispheres to the magnitude range 10-21. It is expected that this and companion work will address many needs of astronomy requiring observations of faint stars and galaxies. In addition, this project will contribute to a database in which standard photometry conducted with a photomultiplier will be compared with photometry obtained with "CCDs" (Charge Coupled Devices).
