The Gattini network consists of three cameras located at the high-altitude Antarctic sites Dome C, Dome A, and South Pole. These star transit cameras monitor wide areas of the Southern sky, taking an image every 5-15 minutes throughout the entire Antarctic winter season. The network has been in operation since the Antarctic 2006 winter season. The award is for the data reduction and subsequent publication of results obtained from more than 3 TB (terabytes) data sets collected by this network to date. The data reduction program will focus on two distinct areas: (1) obtaining photometric light curves of the brightest and most interesting long-period variable stars in the Southern sky, which have known parallaxes and other parameters, and are unique stars with no counterparts in the Kepler spacecraft field; and (2) producing astronomical site testing results that are critical for validating high-altitude Antarctic sites to allow planning of future large astronomical facilities. The broader impacts of this project are in its involvement of an undergraduate student in the project data processing and analyses, as well as the Gattini camera network unique science results could be critical for the validation of future major projects in Antarctic astronomy.

加蒂尼网络由三个摄像机组成，分别位于南极高海拔地区的穹窿C、穹窿A和南极点。这些恒星过境相机监视着南部天空的广阔区域，在整个南极冬季每5-15分钟拍摄一张图像。该网络自2006年南极冬季以来一直在运作。该奖项是为了对该网络迄今收集的超过3tb （TB）数据集进行数据缩减并随后公布结果。数据简化计划将集中在两个不同的领域：(1)获得南方天空中最亮、最有趣的长周期变星的光度光曲线，这些变星具有已知的视差和其他参数，并且是开普勒航天器领域中没有对应的独特恒星；(2)产生天文站点测试结果，这对验证高海拔南极站点至关重要，以便规划未来的大型天文设施。该项目更广泛的影响在于它让一名本科生参与项目数据处理和分析，以及加蒂尼相机网络独特的科学成果可能对南极天文学未来重大项目的验证至关重要。
