丽江站BOOTES-4综述

An Overview of the BOOTES-4 at the Lijiang Observatory

伽马暴与光学暂现源观测系统(Burst Optical Observer and Transient Exploring System,BOOTES)旨在建设覆盖全球的多台软硬件配置相同的全自动望远镜网络,继而实现对γ射线暴和其他瞬变源的快速自动观测。BOOTES-4是该网络中的第4号站,安装在云南天文台丽江观测站。作为中国首个专业程控自主天文台,回顾了BOOTES-4的建设和安装历程,重点介绍其硬件组成和远程望远镜控制系统RTS2的技术特点和优势,最后介绍了该望远镜运行情况和观测成果。

The BOOTES （Burst Optical Observer and Transient Exploring System, http is a global network of Robotic Autonomous Observatories （RAOs）. It was initiated ：//bootes. iaa. es ）, in 1998 under the leadership of Spain and the collaboration of many other countries. It is dedicated to observation of optical emissions from Gamma-Ray Bursts （GRBs） in the Universe. The fourth station of the BOOTES, BOOTES-d, is located at the Lijiang Observatory （of the Yunnan Observatories） in the southwest of China. As the first Chinese RAO the BOOTES-4 has been in full robotic operation since February 2012. It has a set of instruments identical to those of the BOOTES-2, BOOTES-3 , and upcoming BOOTES stations; these include an EMCCD camera on its 0. 6m fast-slewing telescope （BOOTES-4/MET） and an all-sky camera （CASANDRA-4）. In this paper we present the site construction of the BOOTES-4 and details of its hardware/software systems. The hardware systems have been built to meet the scientific requirements and the needed reliability for robotic operation. The Observatory Manager for the BOOTES-4 is the RTS2 （Remote Telescope System, 2nd version）, which is an open-source software system that has been extensively used on many robotic telescopes including all BOOTES ones. We finally describe operational experiences and scientific results obtained with the BOOTES-4 since 2012. With the BOOTES-4 included, the BOOTES now has a larger sky coverage and a more significant role in designated observational tasks than before. The tasks include quick follow-up observation of GRB events, non-stop monitoring of some celestial targets, and acquisition of more precise light curves of GRBs/transient sources.
