南极冰穹A区CSTAR点源表首次发布
The First Release of the CSTAR Point Source Catalog from Dome A, Antarctica
摘要：
2008年1月，中国第24次南极考察队成功地将中国小望远镜ARray（CSTAR）部署到南极高原的最高点DomeA。CSTAR由四个14.5厘米光学望远镜组成，每个望远镜都有不同的滤光片（g，r，i和open），并有4.5度x 4.5度的视场（FOV）。它是高原天文台PLATO的一部分，由机器人操作，每台望远镜在全年黑暗时每30秒拍摄一张图像。在2008年期间，CSTAR #1几乎无故障地执行，在158天的观测期间，在1728小时的总积分时间内获得了超过30万张i波段图像。对于在良好天空条件下拍摄的每张图像，可以检测到超过10，000个低至16等的源。我们对野外所有的光源进行了孔径测光，以创建本文所述的星表。由于CSTAR具有以南天极（Dec =-90度）为中心的固定指向，因此CSTAR的FOV内的所有源被连续监测数月。测光星表可用于研究这些源的任何变化，并用于发现超新星、伽马射线暴和小行星等瞬变源。
英文摘要：
In 2008 January the 24th Chinese expedition team successfully deployed the Chinese Small Telescope ARray (CSTAR) to DomeA, the highest point on the Antarctic plateau. CSTAR consists of four 14.5cm optical telescopes, each with a different filter (g, r, i and open) and has a 4.5degree x 4.5degree field of view (FOV). It operates robotically as part of the Plateau Observatory, PLATO, with each telescope taking an image every 30 seconds throughout the year whenever it is dark. During 2008, CSTAR #1 performed almost flawlessly, acquiring more than 0.3 million i-band images for a total integration time of 1728 hours during 158 days of observations. For each image taken under good sky conditions, more than 10,000 sources down to 16 mag could be detected. We performed aperture photometry on all the sources in the field to create the catalog described herein. Since CSTAR has a fixed pointing centered on the South Celestial Pole (Dec =-90 degree), all the sources within the FOV of CSTAR were monitored continuously for several months. The photometric catalog can be used for studying any variability in these sources, and for the discovery of transient sources such as supernovae, gamma-ray bursts and minor planets.
