AST-0097895LandoltThe goal of Dr. Arlo Landolt's astronomical observational research project is to enhance, develop, and publish faint standard star sequences which are needed for a variety of scientific purposes. There occur projected against the celestial sphere a wide range of phenomena for which observers need intensity and color information. Therefore, there is a long-term need for accurate photometric standard stars, those with known intensities and colors at a variety of optical wavelengths. Use of such standard stars permits the combination and inter-comparison of the brightness and color measurements of different celestial phenomena made by different investigators. Furthermore, Dr. Landolt's standard star work will be an important step toward solving the calibration problems facing the new generation of giant telescopes. ***

AST-0097895 Landolt Arlo Landolt博士的天文观测研究项目的目标是增强、开发和发布各种科学目的所需的微弱标准星星序列。 有发生对天球投影的观测者需要强度和颜色信息的各种现象。 因此，长期需要精确的光度标准星，即在各种光波长下具有已知强度和颜色的标准星。 使用这些标准恒星可以将不同研究者对不同天体现象的亮度和颜色测量结果进行组合和相互比较。 此外，兰道尔特博士的标准星星工作将是解决新一代巨型望远镜面临的校准问题的重要一步。 ***
