The funds from this RAPID proposal are used to replace a broken cooling system for the primary 4Kx4K PixelVision CCD camera on the Yale Southern Observatory (YSO) 51-cm double astrograph located at Cesco Observatory in El Leoncito, Argentina. The Cesco Observatory is operated jointly by the Yale Southern Observatory and the Universidad Nacional de San Juan (UNSJ). The cooling system is essential for operating the primary CCD camera on the astrograph, which is needed to continue currently NSF-funded research through grant AST-0908996, The Milky Way in 3D Velocity Space: A View from the Southern Hemisphere, by Casetti, van Altena, and Girard. That grant was funded under the American Recovery and Reinvestment Act (ARRA) of 2009 (Public Law 111-5).Intellectual Merit: Dr. Casetti and her collaborators work on the Yale/San Juan Southern Proper Motion (SPM) survey. The astrometric observations have been ongoing for decades in order to accurately measure small stellar motions across the sky. The absolute proper motions of stars can be used to determine their orbits around the Galactic center. When such data are compared to dynamical simulations, models of Galaxy formation and evolution can be tested. Together with other observations these measurements are also used to learn about the gravitational potential of the Milky Way Galaxy. Broader Impact: Measurements of the proper motions, positions and photographic photometry for globular clusters and areas along tidal streams and over-densities in the halo and thick disk are made publicly available on a webpage at Yale University. These huge data bases are a valuable resource to the astronomy community for studies of galactic kinematics and structure.The repair of the cooling system will benefit more than one research project as other research group have use for the instrument. This is an international collaboration from researchers in Argentina and the US. Undergraduates at the Universities of San Juan, Cordoba and La Plata in Argentina will be trained as they obtain observations for the project.

该RAPID提案的资金用于更换位于阿根廷El Leoncito Cesco天文台的耶鲁南方天文台（YSO）51厘米双天体照相机上的主4Kx 4K PixelVision CCD相机的损坏冷却系统。Cesco天文台由耶鲁南方天文台和圣胡安国立大学联合运营。冷却系统对于操作天体照相机上的主CCD相机是必不可少的，这是继续目前NSF资助的研究所需的，通过资助AST-0908996，3D速度空间中的银河系：从南半球的观点，由Casetti，货车阿尔特纳和吉拉德。该赠款是根据2009年《美国复苏和再投资法》（《公法》111-5）提供资金的。智力功绩：Casetti博士和她的合作者从事耶鲁/圣胡安南部自行（SPM）调查。天体测量观测已经持续了几十年，以准确测量天空中的小恒星运动。恒星的绝对自行可以用来确定它们绕银河系中心的轨道。当这些数据与动力学模拟进行比较时，可以测试星系形成和演化的模型。与其他观测一起，这些测量也被用来了解银河系的引力势。更广泛的影响：在耶鲁大学的一个网页上公开了球状星团和沿着潮汐流区域的自行、位置和照相测光以及晕和厚盘中的超密度的测量结果。这些庞大的数据库是天文学界研究银河系运动学和结构的宝贵资源。修复冷却系统将有利于多个研究项目，因为其他研究小组也使用该仪器。这是阿根廷和美国研究人员的国际合作。阿根廷圣胡安、科尔多瓦和拉普拉塔大学的本科生将在为该项目进行观测时接受培训。
