南山25米射电望远镜数据

南山25米射电望远镜为修正型卡塞格伦天线，1993年建成并投入使用，经过升级改造后口径扩大到26米，新的26米南山射电望远镜承担着重要的国际合作及国内重大课题的天文观测任务，是欧洲甚长基线干涉网、国际动力测地网、俄罗斯低频VLBI网、东亚VLBI网4个国际合作组织的正式成员。主要开展脉冲星、活动星系核、分子谱线及日变源巡天和监测等多项课题，支持银道面磁场巡天、木星研究等观测。NSRT数据集包括脉冲星、分子谱线和日变源观测数据，NSRT从2010年1月开始使用18厘米制冷接收机和DFB对近300颗脉冲星进行测时观测，DFB数据产生于2010年，每年的原始数据20TB左右。数据发布系统2014年上线。

The Nanshan 25-meter Radio Telescope (NSRT) is a modified Cassegrain antenna. It was completed and put into operation in 1993, and its aperture was expanded to 26 meters after upgrades and retrofits. The new 26-meter Nanshan Radio Telescope undertakes important astronomical observation tasks for international cooperation and domestic major research projects, and is a formal member of four international collaboration organizations: the European Very Long Baseline Interferometry (VLBI) Network (EVN), the International Dynamical Geodetic Network, the Russian Low-frequency VLBI Network, and the East Asian VLBI Network (EAVN). It mainly carries out multiple research programs including pulsar, active galactic nucleus (AGN), molecular spectral line, and diurnal variable source surveys and monitoring, and supports observations such as Galactic plane magnetic field surveys and Jupiter research. The NSRT dataset includes observation data of pulsars, molecular spectral lines and diurnal variable sources. Since January 2010, NSRT has used 18 cm cryogenic receivers and DFB to conduct timing observations on nearly 300 pulsars. The DFB data was generated in 2010, with approximately 20 TB of raw data produced annually. The data release system was launched in 2014.
