Testing and data reduction of the Chinese Small Telescope Array (CSTAR) for Dome A, Antarctica

摘要

The Chinese Small Telescope Array(CSTAR)is the first Chinese astronomical instrument on the Antarctic ice cap.The low temperature and low pressure testing of the data acquisition system was carried out in a laboratory refrigerator and on the 4500m Pamirs high plateau,respectively.The results from the final four nights of test observations demonstrated that CSTAR was ready for operation at Dome A,Antarctica.In this paper,we present a description of CSTAR and the performance derived from the test observations.
