Weights to calculate induced part of magnetic scalar potential in time domain for radially-symmetric conductivity model of the Earth

Weights are calculated based on signal interpolation by sincs with time step of 1 hour and memory 4320 hours. Weights are provided up to degree 5.<br> <br> A sinc concept is explained in Appendices A and B of Kruglyakov et al (2022) "A proper use of the adjacent land-based observatory magnetic field data to account for the geomagnetic disturbances during offshore directional drilling" Space Weather, https://doi.org/10.1029/2022SW003238. 1-D (radially-symmetric) conductivity model is based on Table 1 from Kuvshinov et al (2021) "Probing 3-D electrical conductivity of the mantle using 6 years of Swarm, CryoSat-2 and observatory magnetic data and exploiting matrix Q-responses approach" Earth, Planets and Space, 73, https://doi.org/10.1186/s40623-020-01341-9. The first (surface) layer has 1 km thickness and represents globally averaged conductance ( 9287 S) of landmasses, oceans, and marine sediments.权重基于以1小时为时间步长、记忆时长为4320小时的sinc函数（sinc）对信号进行插值计算得到。权重的最高阶数为5阶。 sinc函数的相关概念可参见Kruglyakov等人2022年发表于《空间天气（Space Weather）》的论文《合理利用邻近陆基观测台站磁场数据以评估海上定向钻井期间的地磁扰动》（DOI: 10.1029/2022SW003238）的附录A与附录B。 一维（径向对称）电导率模型基于Kuvshinov等人2021年发表于《地球、行星与空间（Earth, Planets and Space）》第73卷的论文《利用6年Swarm、CryoSat-2与观测台站磁场数据并结合矩阵Q响应方法探究地幔三维导电性》（DOI: 10.1186/s40623-020-01341-9）中的表1。 第一层（地表层）厚度为1千米，代表全球陆块、海洋与海洋沉积物的平均电导值（9287 西门子（S））。
