Fundamental Optical Photometry

在地面和太空中建造和运行新的大型望远镜需要测量分布在天空中的一系列暗淡恒星的亮度和颜色。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等范围。预计这项工作和其他相关工作将满足天文学对微弱恒星和星系观测的许多需求。此外，该项目将有助于建立一个数据库，其中将用光电倍增管进行的标准光度测定与用“ccd”（电荷耦合器件）获得的光度测定进行比较。

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).
