2025-12-31 Level-1 Data for the First Light of the ArQi Radio Telescope Dedicated to Interplanetary Scintillation Observation doi:10.57760/sciencedb.space.03452 en 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.
