论文摘要
Nanshan一米广场望远镜（NowT）是位于新疆天文学天文台（XAO）的Nanshan站的主要焦点系统。视场（FOV）的设计为1.5度 *1.5度，然后选择Johnson-Cousins Ubvri系统作为主滤镜集。自2013年9月以来，望远镜一直为天文学家提供观察服务。可变来源搜索和时间域调查是主要的科学目标。该系统的测试结果报告包括线性，暗电流，偏置，读数噪声和CCD摄像头的增益。在光度夜间，UBVRI带中的精确仪器校准系数由Landolt标准恒星驱动。最后，限制幅度以信噪比和观察者的各种暴露时间给出。
The Nanshan One-meter Wide-field Telescope (NOWT) is a prime focus system located at Nanshan Station of Xinjiang Astronomical Observatories (XAO). The field of view(FOV) was designed to 1.5 degree *1.5 degree, and Johnson-Cousins UBVRI system was chosen as the main Filter set. The telescope has been providing observation services for astronomers since Sept. 2013. Variable source searching and time-domain surveys are the main scientific goals. The system's test results are reported including linearity, dark current, bias, readout noise and gain of the CCD camera. The accurate instrumental calibration coefficients in UBVRI bands was driven with Landolt standard stars during photometric nights. Finally, the limiting magnitudes are given with signal-to-noise ratios and various exposure times for observers.
