Level-1 Data for the First Light of the ArQi Radio Telescope Dedicated to Interplanetary Scintillation Observation

This FITS file contains the Level-1 Data used in the following paper. Xiong M., Wang W., Su C., et al, First Light for the New 30-Meter Parabolic Radio Telescope at ArQi: Implications for Space Weather Monitoring, Astronomical J., 2026, in press. This is a 2 HDU FITS file containing the following elements:   Filename: OYHGL_IPST01_ISRF_L1_SOB_20240301060800_V01.00.FITS    HDU 0 includes the three-dimensional data in 13500 time points, 2 polarizations, 1 observing frequency. HDU 1 includes the coordinates of each data point in the three dimensions.Additional comments: The radio source of 3C446 at solar elongation of 6.4 degrees was targeted during its 5-minute transit across the antenna beam at ArQi. The receiver is characterized as simultaneous measurements of dual polarizations from 3C446 emission, integrated over a 40 MHz bandwidth around its central frequency of 1.4 GHz.

本FITS文件包含下述论文中使用的L1级数据。熊明、王玮、苏畅等，《阿尔奇（ArQi）30米新型抛物面射电望远镜首光：对空间天气监测的启示》，《天文学期刊》，2026年，已接收待刊。本文件为包含2个表头数据单元（HDU，Header Data Unit）的FITS文件，包含以下内容：
文件名：OYHGL_IPST01_ISRF_L1_SOB_20240301060800_V01.00.FITS
表头数据单元0包含三维数据，涵盖13500个时间点、2个偏振通道与1个观测频率。表头数据单元1包含三维空间中各数据点的坐标信息。
补充说明：本次观测以太阳张角6.4度处的射电源3C446为目标，该源在阿尔奇望远镜的天线波束中历时5分钟过境。本次使用的接收机可同时对3C446的射电辐射进行双偏振测量，积分带宽为以1.4 GHz为中心的40 MHz频段。
