The Alleghany Observatory Photometry Program

该奖项将在阿勒格尼天文台完全翻新的0.76米基勒反射镜上使用双通道斩波光度计。双通道斩波光度计非常适合天文台的需要，因为他们的测光计划的主要兴趣是颜色。此外，对恒星颜色的观测对非光度天气条件不敏感，这在阿勒格尼天文台很常见。根据阿勒格尼天文台的记录，每年平均有120个夜晚适合双通道斩波光度测量。一些天体测量目标恒星是可变的；将观察它们的光曲线，以便可以搜索星等和天体测量位置之间的任何类型的关联。在新的天体测量区域对恒星的光度观测将为天体测量程序选择适当的参考星提供一种有效的方法。

This award will implement a dual-channel chopping photometer for use on the completely renovated 0.76-m Keeler reflector at Allegheny Observatory. A dual-channel chopping photometer is ideally suited to the observatory's needs because the primary interest is in colors in their photometry program. Furthermore, observations of stellar colors are insensitive to the conditions of non-photometric weather, which is common at Allegheny Observatory. According to record books at Allegheny Observatory, there are an average of 120 nights per year which are suitable for dual-channel chopping photometry. Some astrometric target stars are variable; their light curves will be observed so that a search for any type of correlations between magnitude and astrometric position can be made. Photometric observations of stars in new astrometric regions will provide the astrometric program with an efficient method for choosing appropriate reference stars.
