The HAT-South network consists of three pairs of identical, fully automated, wide-field telescopes, each equipped with 4 optics and CCDs forming a mosaic image. The instruments are located at Las Campanas in Chile, Siding Springs in Australia, and the HESS site in Namibia, and are jointly operated by the CfA, MPIA and ANU. Its primary purpose is to search for and characterize extra-solar planets around nearby bright stars. In this presentation I will discuss two aspects of the HAT-South system.
First, in order to achieve the high photometric precision necessary for detecting transiting planets, the observing systems needs to be as stable as possible to minimize systematic noise. Here I will detail the methods used, and the current performance of the fully automated pointing and focus corrections applied during observations.
Second, I will present the frame calibration procedure, and the various diagnostics generated that allow us to monitor the health and performance of such a remote and wide-spread system of telescopes.
